Composition and Inverse. Read the following instructions in order to
complete this assignment:
a. We define the following functions: f(x) = 2x + 5 g(x) = x2 – 3 h(x) = 7
–x
3
§ Compute (f – h)(4).
§ Evaluate the following two compositions: (f g)(x) and (h g)(x).
§ Transform the g(x) function so that the graph is moved 6 units to the
right and 7 units down.
§ Find the inverse functions f -1(x) and h-1(x).
b. Write a two to three page paper that is formatted in APA style and
according to the Math Writing Guide. Format your math work as shown
