_ I 7. In the two questions that follow, the function f(x) _ b is an exponential function. Think carefully about what each graph is showing you. a) The graph of f(x) is shown below. go" 2 f (1') On the same grid, sketch the functions: b) The graph of f (X) is shown below. 8U) _ f'(x) On the same grid, sketch the functions: f'(x) and fur) .f(x) and f'(x)
