Find the cosine function that is represented in the graph.

The cosine function that is represented in the graph is:

Option B. f(x)=cos (x-pi/4)-1

Step-by-step explanation:

The parent function is cos x.

cos x at x=0 has the maximum value 1.

The graph is shifted to the right (x-pi/4) with a maximum value 0 at x=pi/4, then the graph is shifted downward 1 unit.

Then f(x)=cos (x-pi/4)-1

Please, see the attached graph:

The blue line is the parent function y=cos x

The red line is the graph given

step-by-step explanation:

i believe its "c" because all of the other options include a but it could be d because there is a way of financing with cash at certain places but its uncommon.
