Let f(x)= ?xWrite a formula for a function g whose graph is obtained from the graph of f(x) after the following sequence of transformations: (1) shift left 2 units; (2) shift down 4 units; (3) scale vertically by a factor of 2. NOTE: The order you apply the transformations is important and should be done in the order given. It may help to draw the graph after each step, and then determine a formula for thefunction at the end.g(x)=
