Question
Suppose that f is a function given as f(x) = x² + 5x - 3.
Simplify the expression f(x + h).
f(x+h) = x².
-
2xh
h²
+5x+5h30
f(x + h) − f(x)
Simplify the difference quotient,
h
f(x + h) − f(x)
=
h
The derivative of the function at x is the limit of the difference quotient as h approaches zero.
f'(x) =lim
h→0
f(x + h) − f(x)
