Also what about this question?
y = .2 sin ( -8x + 50) + 37
Would this be a vertical compression 0.2, horizontal compression -8, horizontal shift 50, and vertical up 37?
What would be the transformations in this equation?
y = (-x -88) + 76

Would the one above this one be a reflect over y-axis, right 88 up 76?
(-x-88) = -(x+88)
so, shift left 88, then reflect over y-axis
-8x+50 = -8(x-25/4)
so, shift right by 25/4, then horizontal compression by a factor of 8, and reflect across y-axis.
