Two business students at Brock University decided to open a small company together to sell their own brand of sneakers. After doing some research, they estimated that their profit can be modelled by the function x). The graph below is the derivative f'(x) of the function f(x). y 1 '1 y=f(x) Using this graph, the function f(x) has 0 No local maximums or minimums 0 two local minimums at x : -2 and x : 2 and a local maximum atx : 0 0 two local maximums atx : -3 and X : 1 and two local minimums atx : -1 and x : 3 0 two local minimums at x : -3 and X : l and two local maximums atx : -1 and X : 3 0 two local maximums atx = 72 and x = 2 and a local minimum atx = 0 (Q There is not enough information to determine a maximum or minimum
