Question

Identify the absolute extrema for the following function.  

                     f (x) = x3   or    [–2, 2]

Solution

Correct option is

Maximum x = 2 & Minimum x = –2

Here the graph for this function.   

This function has an absolute maximum of eight at x = 2

And an absolute minimum of negative eight at x = –2.
