Find any extreme values of the function f(x) =

- 7 and their locations.
◦ local (and absolute) maximum -7 at x = 5/2, local minimum -2 at x = 0
◦ local (and absolute) minimum -7 at x = 5/2, local maximum -2 at x = 0
◦ local (and absolute) maximum -7 at x = 5/2, no local minima
◦ local (and absolute) minimum -7 at x = 5/2, no local maxima
◦ no absolute or local extrema
