I need help

Given the function g(:o) = 4:33 12:1:2 369:, find the first derivative, g'(a:). W) = Notice thatg'(a:) = 0 when :1: = 1, that is, g'( 1) = 0. Now, we want to know whether there is a local minimum or local maximum at a: = 1, so we will use the second derivative test. Find the second derivative, 9' '.(a:) W) =:] Evaluate g' '( 1). 9\"
