Identify the intervals where f (x) = r+-8-12-16-x is increasing and where decreasing on the interval [-4,4]. Then determine the relative extrema of f(x). Lastly, determine the absolute extrema of f(x). = Please enter a point rather than a number for the extreme values. f'(x) === Click here to start next step f'(x)=0 Click here to start next step 14 3 Analyze the first derivative of f(x) = r + 1-8.r-16-r Intervals Properties (-00,00) + Sign of derivative Increasing/decreasing SELECT TABLE f(x) is increasing: + f(x) is decreasing: (-0, -4]U[-1,4] + Local Minimum: Local Maximum: (-1.0) + (4.- 320) 95 Absolute Minimum: (-1,5) Absolute Maximum: 320 4. 3
