Question

Look at attached question!!

Answer 1

C is the value of the phase shift. What value does cosine normally start at? where did that value of the graph get "shifted" to? How far over that point moved is your phase shift C.

Answer 2

It got shifted 4?

Answer 3

close, but careful, in general when a grapf f(x) is shifted to the right by an amount C the function becomes f(x-C)

Answer 4

Did it get shifted 2?

Answer 5

The magnitude of your shift was correct before. The max value of the cosine now occurs at x=4. we know that the max of the cosine is at cos(0)
So what number C makes it so the maximum occurs at x=4 ? +4 0r -4 ?

Answer 6

I don't know?

Answer 7

read carefully what I said before about the direction of the shift of the graph. I even told you that the magnitude you have for C is correct, you just need to read through what I wrote bit carefully to know whether it is +4 or -4. You can also find references on the internet that would help you. on the concept of graph transformations in general.,

Answer 8

Your answer was wrong! It was 2.
