Answer:
f(g(5)) = 64
 g(f(5)) = 28
Step-by-step explanation:
Given  that f(x) = x^2 and g(x) = x+3
f(g(x) = f(x+3)
f(x+3) = (x+3)^2
f(g(x)) = (x+3)^2
f(g(5)) = (5+3)^2
f(g(5)) = 8^2
f(g(5)) = 64
b) g(f(x)) = g(x^2)
 g(f(x)) = x^2 + 3
 g(f(5)) = 5^2 +3
 g(f(5)) = 25 + 3
 g(f(5)) = 28
Hence the value of g(f(5)) is 28
