f(x)=x* - 18x? 5. Given the function find the intervals where the function is concave up and concave down and find any inflection points. Total = / 14 a)must show work correctly to get credit: {note you must use Calculus. You may use calculator for checking (5) b) Concave up on the interval : [+1] Concave down on the interval: [+1] c) Points of inflection. {give points) [+1] 6. NW Sketch a graph given the following information about the function: (+6] f(0) = 2, f(1) = 0,f(2)= -2; 6 f'(0) = 0, f'(2) = 0; 5 f'(x) > 0 on (-0,0) and (2,00); 4- f'(x) <0 on (0,2); 3 f"(1) = 0; 2 F"(x) > 0 on 1,00); 1 F"(x) <0 on (-0,1) -6.5 4 3 2 1 1 2 3 4 5 6 -1 -2 -3 4 -5 -6 X
