1. The problem statement, all variables and given/known data If the tangent line to y = f (x) at (9,7) passes through the point (0,6), find the following. (a) f (9) (b) f ' (9) 2. Relevant equations f '(x) = f(x+h) - f(x)/h ? 3. The attempt at a solution I really have no idea how to even begin going about this one, so a shove in the right direction would be greatly appreciated.
