Use the table of values to evaluate each expression

Solution

(f o g )(x)\"? This is read as \"f-compose-g of x\", and means \"plug x into g, evaluate, and then plug the result into f\". The computation can feel a lot easier if I use the following, more intuitive, formatting:
(f o g )(x) = f( g(x))
So in this problem, we have (f o g )(8). This means the first step is to plug in 8 into the g(x) function.
Using the given table, we see that when x=8, then. So g(8) = 4

The next step is to take this answer (4), and plug it into f(x).
Again using the table, since x=4, then f(x)=4
So, (f o g )(8) = f(g(8)) = f(4) = 4
Your answer is 4.

7) g(f(5)) = 8

At ,x= 5

f (5) =0

g (f (5)) = g (0) = 8
