Find the inflection points of f(x) = x4 + x3 - 30x2 + 3. Enter the exact answers in increasing order. X = X=Current Attempt in Progress Use the first derivative to find all critical points and use the second derivative to find all inflection points. Use a graph to identify e critical point as a local maximum, a local minimum, or neither. f(x) = x4 - 16x + 11 Enter the exact answers in increasing order. If there are less than four critical points, enter NA in the remaining answer areas and select NA in the remaining dropdowns. The critical point at x = is The critical point at x = is The critical point at x = 15 The critical point at x = is The inflection points are at x = and x = Save for Later Attempts: 0 of 10 used Submit AnsView Policies Current Attempt in Progress Use the first derivative to find all critical points and use the second derivative to find all inflection points. Use a graph to identify each critical point as a local maximum, a local minimum, or neither. f(x) = x - 15x*+55 Enter the exact answers in increasing order. If there is no answer, enter "NA". The critical point at x = is The critical point at x = is V The inflection point is x =(a) Select inflection points if the graph shows f(a). 2 (b) Select inflection points if the graph shows f'(a). (c) Select inflection points if the graph shows f"(x)
