Question 5 (1 point) The graph of a function f is given. Use the graph to answer the question. Find the numbers, if any, at which f has a local minimum. What are the local minima? sty 3- -2 2 O a f has a local minimum at x = -2; the local minimum is 0 Ob f has a local minimum at x = -2 and 2; the local minimum is 0 OC f has a local minimum at x = 0; the local minimum is 2 O d f has no local minimum
