## Difference Quotient

The steps we take to find the difference quot are as follows: Difference Quotient Formula Plug x + h into the function f and simplify to find f (x + h). Now that you have f (x + h), find f (x + h) – f (x) ## Difference Quotient

We first calculate f (x + h). f (x + h) = 2 (x + h)^2 + (x + h) - 2. We now substitute f (x + h) and f (x) in the difference quotient. \dfrac {f (x + h) - f (x)} {h} = \dfrac { 2 (x + h)^2 + (x + h) - 2 - ( 2 x^2 + x - Get detailed step-by-step resolutions
