Question

PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!!

The graph of the function y = x2 is shown. How will the graph change if the equation is changed to y = 2x^2?

Answer 1

The parabola will become narrower.

Explanation:

Because of the coefficient 2, every value of x² is doubled, which means higher value on the same X coordinate, compared to the y = x² function.

Answer 2

Answer: B) The parabola will become narrower

Explanation:

The vertex form of a quadratic equation is: y = a (x - h)² + k where

• "a" is the vertical stretch (shrink/compression if |a| < 1)
• (h, k) is the vertex

In the given equation of y = 2x², the a-value has increased so it is stretched. When the graph stretches, the sides will get closer together thus the parabola will become narrower.
