Suppose that f(x)=x^4−7x^3. (A) List all the critical values of f(x). Note: If there are no critical values, enter 'NONE'. (B) Use interval notation to indicate where f(x) is increasing. Note: Use 'INF' for , '-INF' for −, and use 'U' for the union symbol. Increasing: (C) Use interval notation to indicate where f(x) is decreasing. Decreasing: (D) List the x values of all local maxima of f(x). If there are no local maxima, enter 'NONE'. x values of local maximums = (E) List the x values of all local minima of f(x). If there are no local minima, enter 'NONE'. x values of local mini
You know how to find the critical values at all? or do you know what it means*?
