Find extrema
To find extrema, we need to find the maximum and minimum values of a function
To find extrema, we need to find the maximum and minimum values of a function. There are two types of extrema: absolute extrema and local extrema.
1. Absolute Extrema:
To find the absolute extrema of a function, we need to consider the entire domain of the function. Here’s the general process:
a. Determine the domain of the function.
b. Evaluate the function at the critical points and at the endpoints of the domain.
c. Compare the values obtained in step b to find the maximum and minimum values.
2. Local Extrema:
To find the local extrema of a function, we need to analyze the behavior of the function within a specific interval or at a specific point. Here’s the general process:
a. Determine the interval or point where you want to find local extrema.
b. Determine the critical points within the interval or point of interest.
c. Evaluate the function at the critical points and at the endpoints of the interval/point.
d. Compare the values obtained in step c to find the maximum and minimum values within the interval/point.
It’s important to note that finding extrema sometimes involves using calculus techniques like differentiation or integration when dealing with continuous functions. Additionally, it may also involve using algebraic methods to solve equations and inequalities.
