8) Sketch f(x) = x3-3x + 2 by finding x- intercepts, y-intercept, extrema and inflection points. Be sure to label all important points orn your sketch. 2 2x-8 9) Sketch y = 22-16 by finding x-intercepts, y- intercept, vertical asymptotes, horizontal asymptote and extrema. Label all important features 10) Find the absolute maximum and minimunm values of f(x) on the given closed interval, and state where those values occur. f(x)-x4-2x2 ; [-2,0]
