Finding real values of a function

[ruralkansas]

I am using Excel 97 and was told I can figure algebra problems with it. Any
ideas on how to solve an equation like:
f(x)=12-8x for x=-1; 0; and 1
or
y(x)=3(x-2)w/ exponent 1/2

Thanks! I can't find a function in the list that lets me use the variable x.

Hi
place your X variable values in column A (e.g. A1:A10)
in B1 enter
=12-8*A1
and copy this formula down
