Differentiation to find maximum value

WebApr 10, 2024 · My initial thought is that the function cant be negative, therefore the point (0,0) must be the minimum since it gives the function value of 0. To find the maximum I'll use the partial derivative. f(x, y) = x5y7e − 2x − 2y. I have solved the partial derivatives with respect to x and y. I get the point x= 5/2 and y= 7/2. WebSep 17, 2024 · 3. For cubic function you can find positions of potential minumum/maximums without optimization but using differentiation: get the first and the second derivatives. find zeros of the first derivative (solve quadratic equation) check the second derivative in found points - sign tells whether that point is min, max or saddle point.

WebThe Extreme value theorem states that if a function is continuous on a closed interval [a,b], then the function must have a maximum and a minimum on the interval. This makes sense: when a function is continuous you can draw its graph without lifting the pencil, so you must hit a high point and a low point on that interval. Created by Sal Khan.
