The graph of y = sin x is reflected in the line x = π and then in the line y = 1. Find the equation of the resulting function.

Answer 1

y=sinx reflecting over the line x=pi is the same as flipping the graph upside down

or switching y to -y

-y=sinx

or

y =-sinx

then reflect over the line y=1 flips it upside down again back to where you started

y=sinx, but also shifts it vertically up by 2

y=sinx +2
