Answer: y = 7x²
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
