Consider the function f(x): = 5x³ - 7. 20 4 a. Over what interval(s) is f concave up? (If f is never concave up, enter "DNE".) x = 0,-2,5 b. Over what interval(s) is f concave down? (If f is never concave down, enter "DNE".) c. f(x) has inflection points at what value(s) of x ? (If there are no inflection points, enter "DNE". If f has multiple inflection points, enter the values as a comma-separated list.)
