Question 8 (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 maximum. What are the local maxima? sty 3 -2 -3 O a f has a local maximum at x = 3; the local maximum is 3 Ob f has a local maximum at x = 0; the local maximum is 3 O C f has a local maximum at x = -3 and 3; the local maximum is 0 O d f has no local maximum
