x f(x) g(x)

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)

• Algebra 2 -

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

• Algebra 2 -

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).

• Algebra 2 -

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?
