how to find maximum and minimum value using differentiation The following steps would be useful to find the maximum and minimum value of a function using first and second derivatives
In differential calculus the maxima and minima of a function known collectively as extrema are the largest and smallest value of the function Learn how to find maxima and minima using derivatives at BYJU S In this section we look at how to use derivatives to find the largest and smallest values for a function Consider the function f x x2 1 over the interval As x f x Therefore the function does not have a largest value

Apply a second derivative test to identify a critical point as a local maximum local minimum or saddle point for a function of two variables Examine critical points and boundary points to find absolute maximum and minimum values for a function of two variables How to find the maximum value and minimum value using differentiation I have included examples and 2 practice questions If you need some help with how to fi
Finding the maximum and minimum values of a function also has practical significance because we can use this method to solve optimization problems such as maximizing profit minimizing the amount of material used in manufacturing an aluminum can or finding the maximum height a rocket can reach Locating the point of maximum or minimum The x value at a maximum or minimum is found by differentiating the function and putting it equal to zero The y value is then found by substituting the x into the original equation Example Find the coordinates of the greatest or least value of the function back to top Curve Sketching

Solve the equation f x 0 for x to get the values of x at minima or maxima Determine the value of f x for values a little smaller and a little larger than the x value Decide whether you have a minimum or a maximum Calculate the value of the function at the x value Thus on the interval 1 2 the minimum value is 1 and the maximum is 7 Example 2 Find the Maximum and Minimum Values of f x x 2 4 x 5 on the Interval 0 3 To find the critical points we take the derivative and set it to zero Now we evaluate the function at x 0 x 2 and x 3 So the minimum value on this interval is 1 and the
