Difference Quotient – Definition, Formula, & Examples - The …
The difference quotient of a function measures the average rate of change of $f(x)$ with respect to x given an interval, $[a, a + h]$. Given a function, $f(x)$, its difference quotient tells us the slope of the line that passes through two points of the curve: $(a, f(a))$ and $((a+h), f(a+h))$.

Consider the difference quotient formula. f (x+h)−f (x) h f (x + h) - f (x) h. Find the components of the definition. Tap for more steps... f (x+h) = h2 +2hx+ x2 f (x + h) = h 2 + 2 h x + x 2. f (x) = x2 f (x) = x 2. Plug in the components. f (x+h)−f (x) h = h2 +2hx+x2 −(x2) h f (x + h) - f (x) h = h 2 + 2 h x + x 2 - (x 2) h. Simplify.
Different quotient (and similar) practice problems 1. For each of the following functions, simplify the expression f(x+h)−f(x) h as far as possible. In particular, you should be able to rewrite each expression without an hin the denominator. (a) f(x)=2x+5 (b) f(x)=3−x (c) f(x)=x2 (d) f(x)=2x2 −x (e) f(x)= 1 2 x2 +3x−4 (f) f(x)= √ x (g ...
