Assume that f(x) is continuous for every real num- ber Use the graph of f'(x) to answer the following questions. You do not need to explain your answers. No par- tial credit will be awarded on each part. (a) (2 points) Find all intervals on which the graph of f(x) is concave down. (b) (2 points) Find all intervals on which f(x) is increasing (c) (2 points) Find all values of x at which f(x) has a local (relative) maximum, If there are none, please say so. (d) (2 points) Find all values of x at which f(x) has an inflection point. If there are none, please say so. (e) (2 points) Find all intervals on which the graph of f(x) is concave up. (f) (2 points) Find all values of x at which f(x) has a local (relative) minimum. If there are none, please say so (g) (2 points) Find all intervals on which f(x) is decreasing DELL
