Use the graph below to answer the question that follows: trig graph with points at 0, 2 and pi over 2, 0 and pi, negative 2 and 3 pi over 2, 0 and 2 pi, 2 and 5 pi over 2, 0 and 3 pi, negative 2 What trigonometric function represents the graph?

f(x) = −2 cos(x − pi over 2) f(x) = −2 sin(x − pi over 2) f(x) = 2 cos(x − pi over 2) f(x) = 2 sin(x − pi over 2)

What trigonometric function represents the graph?

 f(x) = −2 cos(x − pi/2) 
 f(x) = −2 sin(x − pi/2 )  
f(x) = 2 cos(x − pi/2)  
f(x) = 2 sin(x −pi/2 )

Answer:

f(x) = −2 cos(x − pi over 2)

Step-by-step explanation:

Because the absolute value of -2 is 2,and cos starts at its maximum
