Revolt · Accepted Answer

⇒ 1: 2, 3, -5; Part 2: -5; Part 3: 3

Question 4

To obtain the graph of y = (x - 8)2, shift the graph of y = x2

Revolt · Accepted Answer

D: right

Question 5

Explain the steps you would use to determine the path of the ball in terms of a transformation of the graph of y = x2.

Revolt · Accepted Answer

/Explanation: Complete the square to get the equation in vertex form with a = -16, h = 1, and k = 19. The path is a reflection over the x-axis and narrower. It is also translated right 1 unit and up 19 units. Which of the following did you include in your explanation? Check all of the boxes that apply.Complete the square to write the equation in vertex form: y = -16(x - 1)2 + 19.Suggest that the graph of the parent function is narrowed, reflected across the x-axis, and then translated 1 unit to the right and 19 units up.
