For the function f(a) = e ( - 7x + 3), use calculus to determine any interval(s) where the function is concave up, any interval(s) where the function is concave down, and any inflection point(s) for the function. f (a) is concave up on f(x) is concave down on f (a) has inflection point(s) atThe graph of the first derivative of p() is shown in the graph below. Use the graph to answer the following questions about p(x) . Use estimations, if necessary. -6 -5 -B -12 -1 UT 6 4 . Over what interval(s) is p(x) decreasing ? p(x) is decreasing on . Over what interval(s) is p(x) concave up ? p(x) is concave up onSketch (on your work paper) the graph of a single continuous function f(x ) that meets all the following conditions. Do not input anything in the answer box below. . f'(x) = 0 for x = - 4, a = 3 . f'(z) is undefined for x = 7 . f'(x) 7 . f' (a) > 0 for a 0 for - 2 > 7
