The function graphed below is option C.
What is Function?A function is a relation from a set A to a set B where the elements in set A only maps to one and only one image in set B. No elements in set A has more than one image in set B.
Given is a piecewise function.
Piecewise functions are function which has different values for different intervals.
Here the two pieces of the function corresponds to the intervals x > 1 and x ≤ 1.
Since the closed circle is over the curve below, we denote the interval x ≤ 1.
Now, from the options, the intervals x > 1 and x ≤ 1 are mentioned in options B and C.
For, x > 1, the graph is increasing. That is, as x value increases y value must increase.
So the equation cannot be x³ - 4.
Hence the option is C.
Hence the correct option is C.

3w = -27 (equation)
Answer:
w = -9
Step-by-step explanation:
Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
3*w-(-27)=0
Step by step solution :
Step 1: Pulling out like terms
Pull out like factors :
3w + 27 = 3 • (w + 9)
Equation at the end of step 1:
Step 2:
Equations which are never true:
Solve : 3 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation:

There are 120 adults in the club. How many children are
there?
Answer:
48 children
Step-by-step explanation:
For every 5 adults there are 2 children.
so for every 1 adult there is 2/5 of a child.
So number of children = 120 * 2/5
= 240/5
= 48.

Plse Help! I'll mark brianleist! A store sells 3000 Halloween-themed wigs at $30 each every month. For each $1 increase in price, they would sell 75 less wigs. What is the price that would minimize the store's revenue? What is the maximum revenue?
PLease show all your work, thank you
Answer:
$15
Step-by-step explanation:
The price that would minimize the store's revenue is $30 + $35 = $65 (a price increase of $35). The maximum revenue is $170,625.
To find the price that would minimize the store's revenue, we need to determine the price at which the wig sales would be maximized.
Let's assume the price increase in dollars is represented by "x" (where x > 0).
The number of wigs sold can be calculated using the given information: for each $1 increase in price, 75 fewer wigs are sold.
So, the number of wigs sold at the price of $30 + x would be 3000 - 75x.
The revenue is calculated by multiplying the price per wig by the number of wigs sold. Therefore, the revenue function (R) can be expressed as:
R = (30 + x)(3000 - 75x)
To find the price that would minimize the store's revenue, we need to find the value of x that minimizes the revenue function. We can do this by finding the critical points of the revenue function.
To find the critical points, we differentiate the revenue function with respect to x and set it equal to zero:
dR/dx = 0
Differentiating R = (30 + x)(3000 - 75x) with respect to x:
dR/dx = (3000 - 75x) + (30 + x)(-75) = 0
Expanding and simplifying:
3000 - 75x - 2250 - 75x = 0
Combine like terms:
-150x - 5250 = 0
Solving for x:
-150x = 5250
x = 5250 / (-150)
x = -35
Since x represents the price increase, a negative value of x would correspond to a price decrease. So, the price that would minimize the store's revenue is $30 - $35 = -$5 (a price decrease of $5).
However, a negative price is not practical in this context. So, we should consider the price increase instead.
Therefore, the price that would minimize the store's revenue is $30 + $35 = $65 (a price increase of $35).
To find the maximum revenue, we can substitute this price ($65) back into the revenue function:
R = (30 + 35)(3000 - 75 * 35)
Simplifying:
R = 65 * 2625
R = $170,625
Therefore, the maximum revenue is $170,625.

There are supposed to be ____ biscuits in a frozen package, but there could be as many as _____ extra or _____ fewer in each bag, depending on the weight of the biscuits. Solving the equality will give the highest and lowest amounts of biscuits in the bag.
Answer:
13, 4, and 4
Step-by-step explanation:
The absolute value of a difference measures the discrepancy between the two numbers inside. The 13 represents the ideal amount of biscuits and x represents the actual number of biscuits in the package. So the difference between the actual and the ideal is 4 (whether it's 4 more of 4 less than 13).
The situation described doesn't actually match the wording, because this says there'll either be 9 or 17 biscuits in the package, due to the "=". If you wanted to have "as many as," then this should be "≤", allowing for 4 or fewer in either direction.

Find the prime factorization of 105 using division by primes. Show work please
Answer:
Factors of 105 are the list of integers that can be evenly divided into 105. There are overall 8 factors of 105 among which 105 is the biggest factor and 1, 3, 5, 7, 15, 21, 35, and 105 are positive factors. The sum of all factors of 105 is 192 and its factors in Pairs are (1, 105), (3, 35), (5, 21), and (7, 15).
Factors of 105: 1, 3, 5, 7, 15, 21, 35 and 105
Negative Factors of 105: -1, -3, -5, -7, -15, -21, -35 and -105
Prime Factors of 105: 3, 5, 7
Prime Factorization of 105: 3 × 5 × 7 = 3 × 5 × 7
Sum of Factors of 105: 192
Step-by-step explanation:
To calculate the factors of 105, we can use the division method. Let's start with 1.
105 ÷ 1 leaves remainder 0.
Since 105 is not an even number, 2 does not divide 105 completely. Thus, it leaves a remainder.
105 ÷ 3 leaves remainder 0.
105 ÷ 5 leaves remainder 0.
105 ÷ 7 leaves remainder 0.
105 ÷ 15 leaves remainder 0.
105 ÷ 21 leaves remainder 0.
105÷ 35 leaves remainder 0.
105 ÷ 105 leaves remainder 0.
Thus, the factors of 105 that we have obtained are 1, 3, 5, 7, 15, 21, 35, and 105.

A student is planning on factoring 4x2 + 36 using difference of two squares (DOTS). Explain why this is an inappropriate method for factoring this expression. Then rewrite the expression by factoring out the greatest common factor (GCF).
This method is not appropriate because of the mathematical sign separating the terms. It is supposed to be minus not a plus sign
The expression by factoring out the greatest common factor is 4(x^2-9)
Given the expression 4x^2 + 36. According to the difference of two square,
a^2 - b^2 = (a-b)(a+b)
For the expression 4x^2 + 36, this can also be written as:
= (2x)^2 + 6^2
= (2x+6)(2x-6)
This method is not appropriate because of the mathematical sign separating the terms. It is supposed to be minus not a plus sign
Using the factoring method:
4x^2 = 4 * x^2
36 = 4 * 9
Since 4 is common to both of the terms, hence;
4x^2 + 36 = 4(x^2+9)
Hence the expression by factoring out the greatest common factor is 4(x^2-9)
