How Do I Set Functions on a TI-89?
How do I set a function of something on the calculator and let the calculator solve for x or any given variable in an expression, according to that function. We may have gone over this in class but for some reason I did not record it in my notes.

u go to f4 click define, then type in the function, ie define(f(x)=x^2)
then u can type in the equation that you need it for....ie: f(8)=64
What i did for that problem was that i went to y= and i typed in 2^x and then for the ratios, i went to the table under Diamond+F5 and did ratios from there.
