Chapter 8.5, Problem 70HP

To determine

To find: The effect on the graph of $y=4x^2$ when the equation is changed to $y=2x^2$ .

Answer to Problem 70HP

The correct choice is (H).

Explanation of Solution

Given:

The equations are $y=4x^2$ and $y=2x^2$ .

Calculation:

Draw the graph of the equations $y=4x^2$ and $y=2x^2$ as follows.

  

The graph is wider than the $y=4x^2$ .

Therefore, the correct choice is (H).
