WebYou can see whether x=2 is a local maximum or minimum by using either the First Derivative Test (testing whether f'(x) changes sign at x=2) or the Second Derivative Test (determining whether f"(2) is positive or negative). However, neither of these will tell you whether f(2) is an absolute maximum or minimum on the closed interval [1, 4], which is … WebWhen you differentiate h, you are not finding the derivative of the concrete value of h (x) (which in your case was h (9)=21). Instead, you are finding the general derivative for the whole function h, and then you plug in your x value of 9 to solve. So the derivative of h (x) is h' (x)= 3f' (x)+ 2g' (x). Then if we need h' (9), we solve:

WebOct 12, 2024 · When x = 0 or y = 0, they vanish, and this answers for ( 0, 0). At this point you can't escape telling more about the derivative of the absolute value. As this function is piecewise linear, its derivative is piecewise constant, and undefined at the angular point (argument = 0 ). Hence the above terms are safe at ( 1, 1), but unsafe at ( 0, 1).
