Answer :- a) f(g(0)) = 46
b) g(f(0)) = 6
Step by step:-
a) To calculate f(g(0), first evaluate g(0), which gives 7 - 02 = 7, and then evaluate f(7), which gives us 7 * 7 - 1 = 46. As a result, f(g(0)) = 46.
b) To calculate g(f(0)), first evaluate f(0), which gives 7 * 0 - 1 = -1, and then evaluate g(-1), which gives us 7 - (-1)2 = 7 - 1 = 6. As a result, g(f(0)) = 6
