Python challenge question to explain

Question

Can someone explain it to me, please?
def f(x):
return g(x) + 3 % 2
def g(x):
return x**2 + 2
print(f(g(1)))

result: 12

What's happening here step by step to get the result?

Answer 1

g(1) = 3
3 % 2 = 1
g(3) = 11
f(3) = g(3) + 1 = 12

Answer 2

Thank you but the order of those functions is really confusing.
