The minimum and maximum of a function on an interval are the extreme values, or extrema (the singular form of extrema is extremum), of the function on the interval. In the given problem, the extremum occurs when x = The specified function is f(x)=-3xx+2= Differentiate f(x) using the product rule. f'(x) = =-3x -3x(x + 2)1/2 (x+2) 2 +(x+2) 1/2 (
