Assume f (x) = 2x+8 and g (*) = 5 what is the value of (g o f) (3)

We first need to find f (3).

f (3) = 2 (3) + 8

f (3) = 6 + 8

f (3) = 14

We now want g (f (3)).

We know that f (3) is 14.

We also know that g (x) is 5.

As you know, 5 is a constant. No matter what the value of x is for g (x), it will not change the value of g (x).

So, g (f (3)) = g (14) = 5.

Answer: g (f (3)) = 5.
