We have

Now, what is f(7)?. - Aug 16th 2008, 09:31 AMblague
thanks for your answer galactus, but unforunately it's not what I'm looking for because I need to use an equation relating to calculus. I'm not sure if this is the equation....

__lim f(x+h)-f(x)__/h [what would*x*and*h*be??] - Aug 16th 2008, 09:55 AMwingless
