Explanation:

The graph of any constant function is a horizontal flat line. The output is the same regardless of whatever input you select. Recall that a one-to-one function must pass the horizontal line test. Horizontal lines themselves fail this test. So this is sufficient to show we don't have a one-to-one function here.

Put another way: Let f(x) be a constant function. Let's say its output is 5. So f(x) = 5 no matter what you pick for x. We can then show that f(a) = f(b) = 5 where a,b are different values. This criteria is enough to show that f(x) is not one-to-one. A one-to-one function must have f(a) = f(b) lead directly to a = b. We cannot have a,b as different values.

----------------------------

The term "onto" in math, specifically when it concerns functions, refers to the idea of the entire range being accessible. If the range is the set of all real numbers, then we consider the function be onto. There's a bit more nuance, but this is the general idea.

With constant functions, we can only reach one output value (in that example above, it was the output 5). We fall very short of the goal of reaching all real numbers in the range. Therefore, this constant function and any constant function can never be onto.

Answer:

D. y + 6 = 3/5 (x-4)

Step-by-step explanation:

Use the given slope and point to substitute into the point-slope formula  y − y 1 = m ( x − x 1 ) .

Slope-intercept form:  y = 3 /5 x − 42 /5

Point-slope form:  y + 6 = 3 /5 ⋅ ( x − 4 )

The given points defines a line from which the linear function can be

determined and the included point on the line can be found.

The point also included on the line is D. [tex]\underline {(9, \, -3)}[/tex]

Reasons:

The given points on the linear function are; (-3, -7), (6, -4)

The slope of the line is given as follows;

[tex]Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

Therefore, we get;

[tex]Slope, \, m =\dfrac{-4-(-7)}{6-(-3)} = \dfrac{1}{3}[/tex]

The equation of the function is therefore;

[tex]y - (-4) = \dfrac{1}{3} \cdot (x - 6)[/tex]

[tex]y = \dfrac{x}{3} - 6[/tex]

Graphing the above equation on the calculator gives the points;

(-9, -9), (3, -5), (12, -2), and (9, -3)

Therefore;

The point also included on the line is D. [tex]\underline {(9, \, -3)}[/tex]

Answer:

Here's how I'd do it

Step-by-step explanation:

Using the appropriate arithmetic operation, the number of snowmen Danny makes is 4

Total number of cotton balls = 14

Number of cotton balls per snowmen = 3

Creating a proportional relationship thus :

3 cotton = 1 snowman

14 cotton balls = x

Cross multiply

3x = 14

Divide both sides by 3

3x/3 = 14/3

x = 4.667

Hence, the number of snowmen that can be made is 4

Step-by-step explanation:

Answer:

The range of y = ex is all numbers greater than 0, so since the function has been shifted up 1, the new range of the function is all numbers greater than 1. Since the argument of any log must be greater than 0, (x-1)/2 > 0. Thus x - 1 > 0, so x > 1

Answer:

defines the set of values [ 1, 2, 3, 4, 5 ], and the range

1 : 3 : 5

defines the set of values [ 1, 4 ].

Although a range constant specifies a row vector, Octave does not normally convert range constants to vectors unless it is necessary to do so. This allows you to write a constant like 1 : 10000 without using 80,000 bytes of storage on a typical 32-bit workstation.

A common example of when it does become necessary to convert ranges into vectors occurs when they appear within a vector (i.e., inside square brackets). For instance, whereas

x = 0 : 0.1 : 1;

defines x to be a variable of type range and occupies 24 bytes of memory, the expression

Step-by-step explanation:

f(x) = x²

g(x) = 5x

h(x) = x + 4

= h[f(4)]

= x + 4

= f(4) + 4

= (4)² + 2

= 16 + 2

= 18

h[f(4)] = 18

Step-by-step explanation:

Hi I hope u have a great time ...

CD = FE

thus :

[tex]3x + 5 = 7x - 39[/tex]

Add both sides 39

[tex]3x + 5 + 39 = 7x - 39 + 39[/tex]

[tex]3x + 44 = 7x[/tex]
