Part a & d only:

Consider the following function. f ( x ) = - x - 2 3x + 5 (a) Find the inverse function of f. f - 1 ( x ) = (b) Graph both f and f on the same set of coordinate axes. y 15 -1 10 10 5 5 15 -10 -5 10 15 15- 10- = X 5 10 15 -5 f1 -10 10 O 4 . 4 15 15 10 10 5 5 15 -10 -5 5 10 15 - 15 -10 -5 -51 -10 - 10 -15 (c) Describe the relationship between the graphs of f and f-1. The graph of f is the same as the graph of f. The graph of f is the reflection of f in the y-axis. . The graph of f is the reflection of f in the line y = X. The graph of f is the reflection of f in the x-axis. The graph of f is the reflection of f in the line y = -X.(d) State the domain and range of 1".
