The graph of a function f is given. Use the graph to find each of the following.a. The numbers, if any, at which f has a relative maximum. What are these relative maxima?b. The numbers, if any, at which f has a relative minimum. What are these relative minima?The coordinates are shaped like an W. The 1st coordinate is 0.5,5. The 2nd coordinate is 0,1. The 3rd coordinate is 1,5. The 4th coordinate is 2,1. The 5th coordinate is 2.5,5
