Question

Choose the function whose graph is given by:



A. y = sinx - 2
B. y = sin(x + 2)
C. y = cos(x - 1)
D. y = sin(x - 2)

Answer 1

I think its D.

Answer 2

Its a sinx graph that is shifted 2 units two the right.
That means that every value of x is first reduced by two to get the value that you would have gotten had it not been shifted.
Example, In the graph At x = 2 y=0.
sin(2-2) = 0 too.
