Find the difference quotient of f, that is, find [f(x + h) - f(x)]/h, where h cannot = 0, for the given function.

Be sure to simplify.

f(x) = (x+3)^2

f(x)=3x^2-5x+4

g(x)=x-3

NOTE: This question comes from a pre-calculus textbook and so the explanation must be in pre-calculus terms andNOTcalculus.

Thankx.
