1. Graph the function by finding the following information. f(x) = -0.25x4 - x3 a) Find the domain and intercepts Domain: x-intercepts:_ y-intercepts:c) Find the partition numbers for f"(x), determine intervals on which f is concave up/down and find the inflection points of f if any (order pair), use the information found from part a,b, and c to graph b) Find the partition numbers for f'(x), the critical numbers for f (x), the intervals the function. where the function is increasing and decreasing and the order pair of local max and local min if any. Critical Points: Increasing: Decreasing: Concave up: Local Max : Concave down:_ Local Min: Point(s) of inflection
