Answer to Problem 4E

A function value f ( a ) is a local minimum value of f if f ( a ) is the lowest value of f on some interval containing a . From the graph of f , we see that one local minimum value of f is 2 and that this value occurs when x is 4 .

Explanation of Solution

Given information: A function value f ( a ) is a local minimum value of f if f ( a ) is the ______ value of f on some interval containing a . From the graph of f , we see that one local minimum value of f is _____ and that this value occurs when x is ______.
