Difference Quotient - Math is Fun
It gives the average slope between two points on a curve f (x) that are Δx apart, and is used with derivatives: Example: f (x) = x2 − 2x + 1 at x = 3 and Δx = 0.1 Evaluate f (x) at x=3: f (3) = 3 2 − 2×3 + 1 = 4 Now for f (x+Δx): f (3.1) = (3.1) 2 − 2×3.1 + 1 = 4.41 And the Difference Quotient is: f (3.1) − f (3) 0.1 = 4.41 − 4 0.1 = 0.41 0.1 = 4.1

Difference Quotient: Definition & Example - Statistics How To
The difference quotient is one way to find a derivative or slope of a function. The formula is: It might look intimidating, but it’s easier to solve than it looks, because many of the terms cancel out. It’s called a “difference quotient” because the formula has two parts: a difference (subtraction) in the numerator and a quotient ...

Difference Quotient - Definition, Formula, and Examples
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)).

Difference Quotient - Formula, Calculator, Examples
The difference quotient is a measure of the average rate of change of the function over an interval (in this case, an interval of length h). The limit of the difference quotient (i.e., the derivative) is thus the instantaneous rate of change. Difference Quotient Calculator. f (x) =.
