Question 11 Second Derivative Test 1. Find the first derivative of the function g(x) = 8x + 60x2 + 144x. g'(x) = 2. Find the second derivative of the function. 3. Evaluate g"( - 3). 8" ( - 3 ) = 4. Is the graph of g(I) concave up or concave down at r = - 3? At x = - 3 the graph of g(x) is concave 5. Does the graph of g() have a local minimum or local maximum at a = - 3? At x = - 3 there is a local Check
