[f(a+h)-f(a)]/h

- precalculas -
**drwls**, Saturday, February 26, 2011 at 1:41amYou will have to pick a value of a and of h. If you want a general expression for

[f(a+h)-f(a)]/h with that function, it would be

[4(a+h)^2 - 4a^2]/h

= (8ah +h^2)/h

= 8a +4h

Note that it approaches a constant 8a when h->0

That is called the derivatve of the fucntion at a.
