**Reiny**, Saturday, April 4, 2009 at 5:08pmmake a table of values for x and y

(f(x) is really y,

f(x) = x^2 is the same as y = x^2

x y

0 0

1 1

2 4

3 9

-1 1

-2 4

-3 9

graph these points, they should give you a good outline of the curve.

for something like

f(x) = 3x - 3

then f(4) = 3(4)-3 = 9

wherever I saw an x, I subbed in a 4

you can now do the rest
