la fonction f(x) le graphique ci - dessous représente la valeur relative. combien de points sur ce graphique représentent une valeur extrême ?

Explanation:

Step1: Identify relative extrema

A relative (local) extremum is a point where the function changes from increasing to decreasing (local maximum) or decreasing to increasing (local minimum).

• Point b: Local maximum (function changes from increasing to decreasing)
• Point c: Local minimum (function changes from decreasing to increasing)
• Point e: Local maximum (function changes from increasing to decreasing)
• Point g: Local minimum (function changes from decreasing to increasing)

Points a, d, f, h are intercepts where the function does not change direction in a way that creates an extremum.

Step2: Count the extrema

Count the identified local extrema: b, c, e, g.
