1. The graph of y = f(x) is a parabola whose vertex is at (1, -2). The graph of y = f(x - 3) is also a parabola. Where is the vertex of the graph of y = f(x-3)? Write your answer as an ordered pair.
2. The graph of has the line as an axis of symmetry. The graph also passes through the point. Find another point that must lie on the graph of y = f(x).
3. The graph of y = f(x) is shown in the first picture in red. Find the equation that corresponds to the blue graph.
Enter your answer in the form "y = …".
4. The graph of y = h(x) is shown in red in the second picture. Compute h(h(7)).
(Assume grid lines are spaced 1 unit apart.)
5. In the third picture is a portion of the graph of a function, y=u(x):
What is the exact value of u(-2.72)+u(-0.81)+u(0.81)+u(2.72)?
Answers
Answer:
Q1The graph of y = f(x), has vertex at (1, -2)
The vertex of a function f(x - 3) is going to be:
(1 - 3, -2) = (-2, -2)Q2The graph of y = f(x) has the line x = 5 as an axis of symmetry. The graph also passes through the point (8,-7). Find another point that must lie on the graph of y = f(x).The axis of symmetry is at the same distance from the symmetric points.
x = 5 is a vertical line. The point (8, -7) is 3 units to the right. So the mirror point will be 3 units to the left and have same y-coordinate: x = 5 - 3 = 2
The point is (2, -7)
Q3The graph in blue is the translation of the red to the left by 2 units.
So the equation is:
y = f(x + 2)Q4y = h(x) is graphed
h(7) = 5h(h(7)) = h(5) = -1Q5The graph of the function y = u(x) given
This is a odd function.
The coordinates of u(x) and u(-x) add to zero because u(-x) = -u(x)
Therefore:
u(-2.72) + u(-0.81) + u(0.81) + u(2.72) = [u(-2.72) + u(2.72)] + [u(-0.81) + u(0.81)] = 0 + 0 = 0Related Questions

Write and simplify an expression to represent the perimeter of a rectangle whose length is twice the width.
Answers
Answer: 2x+4x
Step-by-step explanation:
Let's say x is the width, or the short side and 2x is the long side or length (since the long side is twice as long as the short side).
let's add those together.
x+2x
But with a perimeter, you have two short sides and two long sides. so let's multiply this expression by two.
2(x+2x)
multiply the two by each number.
2x+4x

Answer:
b = 17.55
Step-by-step explanation:
a^2 + b^2 = c^2
4^2 + b^2 = 18^2
16 + b^2 = 324
-16 -16
b^2 = 308
square root them
b = 17.55
let me know if it is correct!
Step-by-step explanation:
4^2 + h^2 = 18^2
16 +h^2 = 324
h^2 = 308
h = √308
h = 17.5499 ft
Cody and Jordan were selling Flamin' Hot Cheetos to raise money for the Tornados. Cody sold 5 bags of Cheetos for every 3 bags Jordan sold. Together they sold 160 bags total. How many bags did each boy sell?
Answers
They sold 160 and for each 5 bags sold by one 3 bags are sold by another 3+5=8.
160/8=20.
Now Since Cody Sold 5 Bags for every 3 bags for Jordan
5x20=100
3x20=60
Cody Sold 100 and Jordan Sold 60
Answer:
cody sold 100 & jordan sold 60
