Answer 1

Answer:  5

=======================================================

Explanation:

From the table, we see that g(1) = 0

Locate x = 1 in the first row. Then look straight down to see 0 in the g(x) row. That's why g(1) = 0.

This means f( g(1) ) = f( 0 ). I simply replaced g(1) with 0.

The last step is to evaluate f(0).

Locate 0 in the x row. Then look down to see 5 below it. Therefore, f(0) = 5.

Ultimately, f( g(1) ) = f(0) = 5

------------

In short: the input x = 1 leads to g(x) = 0. Then x = 0 is the input for f(x) which leads to 5.
