Answer: y = 7x²

Step-by-step explanation:

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

  • "a" represents the vertical stretch
  • "h" represents the shift to the left (or right)
  • "k" represents the shift up (or down)
  • (h, k) represents the vertex

Given the parent function y = x², a vertical stretch by a factor of 7 means the a-value is 7    ⇒      y = 7x²
