Step 1
Critical points occur when the derivative is equal to zero or undefined. To find the derivative of f(x), we can use the power rule: f'(x) = 18x^2 - 18x + 756 Now, let's set the derivative equal to zero and solve for x: 18x^2 - 18x + 756 = 0 We can simplify Show more…

Consider the following function: f(x) = 2x^3 + 9x^2 - 24x. (a) Find the critical numbers of f. (Enter your answers as a comma-separated list.) x = (b) Find the open intervals on which the function is increasing or decreasing. (Enter your answers using interval notation. If an answer does not exist, enter DNE.) increasing decreasing (c) Apply the First Derivative Test to identify the relative extremum. (If an answer does not exist, enter DNE.) relative maximum (x, y) = relative minimum (x, y) =
