h. – represents the change in x or (x2 – x1) or ∆x. f (x+h) – f (x) – represents (y2 – y1) What is H in derivative function? f(a+h)−f(a)h. is the slope of the line through the points (a,f(a)) and (a+h,f(a+h)), the so called secant line. What does H mean in limits? Right hand […]

The steps we take to find the difference quotient are as follows: 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) by plugging in f(x + h) and f(x) and simplifying. Plug your result from step […]
