Consider the function f(x) - 12x 4 45x -80x + 2. If(x) has inflection points at (reading from left to right) x = D, E, and F where D is and E is and F is For each of the following intervals, tell whether f(r) is concave up or concave down. (- co, D): Select an answer (D, E): Select an answer V (E, F): Select an answer V (F, co): Select an answer V
