Part One: Evaluate the function f(x) = 5x^2. Locate the critical points of the given function f(x) = x^3 + 3x. Use the First Derivative Test to locate the local extrema values of the function. Determine if the absolute maximum and minimum values of the function exist. Locate the critical points of the given function. Select the correct choice below and enter your answer in the Answer Box - complete your choice, critical point(s) are (-6, 51). Your answer: Use common sense. The correct choice is (-6, 51). The maximum value of the function occurs at the critical point.
