Take a look at the table below and compute an equation for f(x).
x : -3 -2 1 3 4
f(x) 0 3 12 18 21
-------------------------
Fill in the missing "x" values and you
will see you are missing (-1,6),(0,9), and (2,15)
----
Since f(x) increases by 3 when x increases 1,
you know the slope is 3.
Since f(x) = 9 when x = 0, you know the intercept
is 9.
--------------
Equation: f(x) = 3x+9
