Use a graphing utility to graph the function over the indicated interval and approximate any local maxima and local minima. Determine where the function is increasing and where it is decreasing. If necessary, round answers to two decimal places.f(x) = 0.15x4 + 0.3x3 - 0.8x2 + 5; (-4, 2)
What will be an ideal response?
local maximum at (0, 5)
local minima at (-2.55, 1.17) and (1.05, 4.65)
increasing on (-2.55, 0) and (1.05, 2)
decreasing on (-4, -2.55) and (0, 1.05)
