Question

How does the graph of f(x) = |x| compare with the graph of g(x) = -2|x|? a. The graph of g is a vertical compression of the graph of f b. The graph of g is a vertical stretch of the graph of f C. The graph of g is a reflection over the x-axis of the graph of fD. The graph of g is a vertical stretch and a reflection over the x-axis of the graph of f

Answer 1

According to the given functions, there are two transfomations in place, a vertical stretch and a reflection across the x-axis because they coefficient is negative and greater than 1.

Hence, the right answer is D.
