Question

Suppose that f(x) = (11 - 5x)ex. Note: Several parts of this problem require answers entered in interval notation. Note, with interval notation, you can enter the empty set as {}. List all the critical values of f(x). Note: If there are no critical values, enter NONE. Use interval notation to indicate where f(x) is increasing. Increasing: Use interval notation to indicate where f(x) is decreasing. Decreasing: List the x values of all local maxima of f(x). If there are no local maxima, enter NONE, x values of local maximums = List the x values of all local minima of f(x). If there are no local minima, enter NONE, x values of local minimums = Use interval notation to indicate where f(x) is concave up. Concave up: Use interval notation to indicate where f(x) is concave down. Concave down: List the x values of all the inflection points of f. If there are no inflection points, enter NONE, x values of inflection points =
