Question

What cosine function represents an amplitude of 3, a period of π, no horizontal shift, and a vertical shift of 2?

Answer 1

I got f(x) = 3 cos 2x + 2 ?

Answer 2

Answer 3

can you show your work..??
yur answeer is most likely to be true...!!!

Answer 4

well the amplitude is in the front so 3, its a cosine function so 3cos, (the period is either pi or 2, im not to sure) and the veertival shift is 2 so 3cos(?x)+2

Answer 5

what are the chooices..???

Answer 6

f(x) = 2 cos 2x + 3

f(x) = 3 cos πx + 2

f(x) = 2 cos πx + 3

f(x) = 3 cos 2x + 2
