Answer 1

cos(x)

Answer 2

or sin(x-pi)

Answer 3

but the answer that you are looking for would be cos(x)

Answer 4

but these are the choices:
f(x) = 2cos x
f(x) = 3cos x
f(x) = 1/2 cos x
f(x) = 1/3 cos x

Answer 5

oh its 1/2cos(x)

Answer 6

didnt see it only went to +/-(1/2)

Answer 7

because the amplitude of the graph is (1/2) the leading coefficient is the amplitude.

Answer 8

What is the domain of the function y = tan x?

Answer 9

1/2 cos(x) is the answer. The graph simply shows cosx. The amplitude 0.5.
