Difference Quotient - Definition, Formula, and Examples
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)). Let’s visualize this to better understand the concept of the difference quotient.
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 ...
