The graph of y=h(x) is shown below. The function f(x) is defined by f(x) = -1/2 h(x) +3.
A) what three transformations have occurred to the graph of H to produce the graph of F? Specify the transformations in the order they occurred in.
B) graph and label the function F(x) on the grid below that contains H(x).
