x f(x) g(x)

2 5 0

3 7 1

4 9 2

5 11 3

What is the equation of g(x) ?

What is g(g(4)) ?

Name a point on the graph of g(x)

The table didn't turn out very good so here it is another way:

x: 2, 3, 4, 5

f(x): 5, 7, 9, 11

g(x): 0, 1, 2, 3

g(x) = x-2

g(4) = 2

g(g(4)) = 0

They have already provided you with four points on the g(x) curve. Ignore the data on f(x).

Notice f(x) and g(x) increase by two, and one, for each increase in x.

f(x)=2x+1

g(x)=x-2

Will that do it?
