The Derivative tells us! Using derivatives we can find the slope of that function:. A derivative basically finds the slope of a function. Take the derivative of the slope the second derivative of the original function :. A slope that gets smaller and goes though 0 means a maximum.

On the graph above I showed the slope before and after, but in practice we do the test at the point where the slope is zero :. We say local maximum or minimum when there may be higher or lower points elsewhere but not nearby. If you've found an issue with this question, please let us know.

### How to Find the Minimum or Maximum in a Quadratic Equation

Possible Answers: Cannot be determined. Correct answer:. Explanation : To find relative maximums, we need to find where our first derivative changes sign. Report an Error. Possible Answers:. Determine the relative maxima for the function:.

Explanation : To determine the relative maxima for the function, we must determine where the first derivative of the function changes from positive to negative. Points of inflection A point of the graph of a function at which it crosses its tangent, and concavity changes from up to down or vice versa is called the point of inflection.

Applications of differentiation - the graph of a function and its derivatives. Extreme points, local or relative maximum and local minimum.
