Question

Use the tables of values of f and g to answer the problem.

(gof)(2) =

x f(x)
2 3
4 8
6 14
13 18

x g(x)
0 0
2 4
3 9
4 16

Answer 1

(gof)(2) = g(f(2))
Find f(2) from the f(x) table. That means: when x = 2, what is f(x)?
Take the answer you found above for f(2) and treat that as x.
Then look up the g(x) table for that x value
And that will be g(f(2))

Answer 2
