Correct answer only !

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

B) The parabola will become narrower

Step-by-step explanation:

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

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.

the solution is 12x-6y

it is true
