16. State the domain and range of the given function. If the function is bijective, find the inverse. If not, find the largest subset U ER that you can on which f is injective, then find the inverse. In either case, state the domain and range of the inverse. (a) (10 points) f(x) =6x -5 (b) (10 points) f(x) =x2+1 (c) (10 points) f(x) = x+2 (d) (10 points) f(x) = csex
