5

Step-by-step explanation:

Evaluate g (0) then substitute the value obtained into f (x)

g (0) = 0² + 2 = 0 + 2 = 2, then

f (2) = 3 (2) - 1 = 6 - 1 = 5

5.

Step-by-step explanation:

To find (f o g) (x) we replace the x in f (x) by g (x):

(f o g) (x) = 3 (x^2 + 2) - 1.

So (f o g) (0) = 3 (0^2 + 2) - 1

= 6 - 1

= 5.
