a) f(g(0)) = 16.
b) g(f(0))=2.
To find f(g(0)), we first need to find g(0) and then plug that value into f(x). Similarly, for g(f(0)), we find f (0) and then plug that value into g(x).
Let's calculate:
(a) f(g(0)):
First, find g(0): g(0) 3 (0)2 = 3
Now, plug g (0) into f(x): f(g(0)) = f(3) = 53+1=15 + 1 = 16
So, f(g(0)) = 16.
(b) g(f(0)):
First, find f (0): f(0)=50+1=1
Now, plug f(0) into g(x):
g(f(0))=g(1)=3−
=3−1=2
So, g(f(0))=2.
