Answer: B) the graph will become narrower
Explanation:
The general form of a quadratic function is: y = a(x - h)² + k where
- a is the vertical stretch
- (h, k) is the vertex
- h is the shift left or right, k is the shift up or down
The given equation has an a-value of 2, so the graph is stretched by a factor of 2 --> which means the parabola becomes narrower.
