Please help!!

1. I don't know how to solve for the coordinates using the functions below. Ps. I know the right answers, but I don't know how to get there. Please show me solving the coordinates using function a) and c) in detail.
   

2. Given the graph of y = f(x) and each of the following transformations, . state the coordinates of the image points A', B', C', D' and E' . sketch the graph of the transformed function a) g(x) = f(x) + 3 b) h(x) = f(x - 2) c) s(x) = f(x + 4) d) t(x) = f(x) - 2 VA y = f(x) 2 B C -4 -2 0 X m A 2 D3. Describe, using mapping notation, how the graphs of the following functions can be obtained from the graph of y = f(x). a) y = f(x + 10) b) y + 6 = f (x) c) y = f (x - 7)+ 4
