WebSolving this equation for x, we find that x = 1 and x = 11/3 are the critical points. To determine if these critical points correspond to maximum or minimum values, we can examine the second derivative of f(x): f''(x) = 6x - 12. Since f''(x) is positive for all x, this means that f(x) is concave up and that its critical points correspond to ...
