# Use the graph below to answer the question that follows: trig graph with points at 0, negative 4 and pi over 2, 0 and pi, 4 and 3 pi over 2, 0 and 2 pi, negative 4 and 5 pi over 2, 0 and 3 pi, 4 What trigonometric function represents the graph? f(x) = 4 sin(x − pi over 2) f(x) = 4 cos(x − pi over 2) f(x) = 4 sin(x − pi over 2) + 1 f(x) = 4 cos(x − pi over 2) + 1

The only correct function is $f(x)=4sin(x-\frac{\pi}{2})$
