Answer:

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: 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.
