Consider the function f(x) = x- 2x - 4x + 8 on the interval [-1, 3]. Find f'(x). 2 f'(x)=3x-4x-4 Nicely done! Find the critical values. --22 X = 3 .2 That's it! Evaluate the function at the critical values. (x, y) = (x, y) = (smaller x-value) (larger x-value) Evaluate the function at the endpoints of the given interval. (x, y) = I (x, y) = = (smaller x-value) (larger x-value) Find the absolute maxima and minima for f(x) on the interval [-1, 3]. absolute maximum (x, y) = absolute minimum (x, y) = =
