The graph of F(x) can be stretched vertically and flipped over the x-axis to produce the graph of G(x). If F(x) = x2, which of the following could be the equation of G(x)? A. G(x) = 4x2 B. G(x) = -1/4x2 C. G(x) = -4x2 D. G(x) = 1/4x2

If it is stretched vertically then the answer is between A and C. What is in front of the x^2 must be greater than 1
In other words if y = ax^2 then a must be greater than 1

If it is flipped over the x axis then the answer is C.
