Find the difference quotient for a quadratic in standard form

Learn how to evaluate the limit of a function using the difference quotient formula. The difference quotient is a measure of the average rate of change of the function over an interval, h. The limit of the difference quotient gives the derivative of the function. The difference quotient formula states that the derivative of a function f(x) is the limit as h goes to zer0 of the quotient of the diference between f(x + h) and f(x) and h.
