How does the graph of f(x)=4cos(1/2x)-3 differ from the graph of g(x)=4cos(x)-3

A. The graph of f(x) is compressed horizontally
B. The graph of f(x) is stretched vertically
C. The graph of f(x) is compressed vertically
D. The graph of f(x) is stretched horizontally

Answer 1

It will be horizontally since it only affects the X. It will be a stretch of 2, since for horizontal you take the opposite 1/2 -> 2/1 = 2.

Answer 2

Answer is D.
