9. Find (using both algebra and calculus) the absolute maximum and minimum over the interval [-1, 4] for f(x) = x3 - 3x2 +2 (4 pts.) Use g(x) = 3x-1 2 x+5 (5 pts. each) Hint: refer to #2 10. Find and discuss: a) the critical values for fusing the first derivative and the number line in order to b) name the intervals where f is increasing/decreasing, and c) name the local extrema points: 1. Find and discuss: a) the second derivative and the number line to describe: b) the intervals where f is concave up/ down and name c) any points of inflection
