I'm doing a test and i need help ! How does the graph of f(x) = |x| compare with the graph of g(x) = −2|x|?

Select all that apply.

The graph of g is a vertical compression of the graph of f.

The graph of g is a vertical stretch of the graph of f.

The graph of g is a reflection over the x-axis of the graph of f.

If cos(2x) = tan^2(y), show that cos(2y) = tan^2(x).
