Identify all of the global and local extrema of the graph. 10 a.) 16 is a global maximum of fix) at x = 2. O -1 is a global minimum fix) at x =1. 7 is a local maximum ofx) at x = - 1. b.) 16 is a global maximum of x) at x = 2. O -1is a global and local minimum ofx) at x =1. 7 is a local maximum ofx) at x = - 1. c.) 16 is a global maximum of x) at x = 2. O -1 is a global and local minimum x) at x =1. d.) 16 is a global maximum of x) at x = 2. O -1 is a global minimum of x) at x =1
