here is a graph of the function f. use the graph to find the following. if there is more than one answer, separate them with commas. (a) all local maximum values of f: (b) all values at which f has a local maximum:
Answer
Explanation:
Step1: Identify local maximum points
Local maximum points are peaks on the graph where the function changes from increasing to decreasing.
Step2: Determine local - maximum values
The local - maximum values are the $y$ - coordinates of the local - maximum points. From the graph, the local - maximum values occur at $y = 3$.
Step3: Determine $x$ - values of local maximum
The $x$ - values at which the local maximum occurs are the $x$ - coordinates of the local - maximum points. From the graph, the function has local maxima at $x=-1$ and $x = 3$.
Answer:
(a) 3 (b) -1,3
