How to Find Local Extrema with the First Derivative Test

WebThe local extrema are found by solving the derivative of the function equal to zero. This is because at local extrema, the derivative changes sign from positive to negative (for a maximum) or negative to positive (for a minimum). So, setting the derivative equal to zero and solving for the critical points will give us the locations of the local ... Webmaximum values. That is, extrema are the points of a function where it is the largest and the smallet. We can identify two types of extrema - local and global. Global extrema are the largest and smallest values that a function takes on over its entire domain, and local extrema are extrema which occur in a speciﬁc neighborhood of the function.
