Consider the function f(x) = x - 8 - 30x + 13. a) List all the critical values of f(x). Note: Give your answer as a comma separated list eg. "1,2,3" without quotes. If there are no critical values, enter 'NONE' without quotes. b) List the x values of all local maxima of f(x). Note: Give your answer as a comma separated list eg. "1,2,3" without quotes. If there are no critical values, enter 'NONE' without quotes. x values of local maxima = c) List the x values of all local mimima of f(x). Note: Give your answer as a comma separated list eg. "1,2,3" without quotes. If there are no critical values, enter 'NONE' without quotes. x values of local minima = f) List the x values of all the inflection points of f. Note: Give your answer as a comma separated list eg. "1,2,3" without quotes. If there are no inflection points, enter 'NONE' without quotes. x values of inflection points: = g) Use interval notation to indicate where f(x) is concave up. Note: Use "INF" and "-INF" without quotes to represent infinity and -infinity respectively. Concave up: h) Use interval notation to indicate where f(x) is concave down. Note: Use "INF" and "-INF" without quotes to represent infinity and -infinity respectively. Concave down:
