2. Consider the function f that satisfies the following: f is continuous everywhere except at x = − -1,2, f has an x-intercept at x = : 1, f has a y-intercept at y = − -1, lim f(x) = ==∞ = lim f(x), lim f(x) = +∞ = lim f(x), lim f(x) = 0, and x→-1+ x-2- x+2+ -1-1x the table of signs for f' and f" are given below: f'(x) f"(x) (-∞, -1) -1 (-1,1) 1 (1, 2) und. + 0 + und. 0 + 8+←æ 2 und. und. (2, +∞0) + b. Determine the intervals where f is increasing or decreasing and where f is concave up or concave down. Identify the relative extremum points and points of inflection, if there are any.
