6. (10 pts) For the given graph of function f, solve f (x) 2 0. . 204 -16- . ..:. . 7. 8. . .9 10 7. (8 pts) The graph of exponential function f is shown in each part, (a) - (d). Use this graph to sketch the indicated functions for (a) - (d). Assuming that three key points of the parent function, shown on the graphs below, are (-2, 1/4), (0, 1), and (2, 4), label at least two key points on each graph you sketch. a. y = f(x - 4) b. y =-f(x) ff(x) =ax ty ff ( x ) =ax C . y = f(x) - 3 d. ty ff (x ) =ax y = f- 1 (x ) ty ff ( x ) = at1. (10 pts) For f (x) = 3x2 + 5x and g(x) = 4 - 8x, find the following [simplify part (a) ]: a. (fog) (x) = b . (g - f) ( - 3) = 2. (10 pts) Find the inverse of the one-to-one function f(x) = 5x3 - 9. f - 1 (x) = 3. (10 pts) Verify that f(x) = 2x+3 and g(x) = 2x-3 - are inverse functions. (f . g ) ( x ) = ( g . f ) ( x ) =
