Use the limit definition to find the derivative of f(x) = x2 ­ 5x
Definition of a Derivative
The derivative of f at x is given by provided the limit exists
The derivative f'(x) is a formula for the slope of a tangent line to the graph of f at the point (x,(f(x))

Find f'(x) for f(x) = √x. Then find the slope of the graph at the points (1,1) and (4, 2)
The derivative IS the slope of the tangent line, so to find it just plug the x­value of the point into the derivative. May 11­2:01 PM
