Use this difference quotient calculator to find how much a function changes on average over a specific interval. Our tool displays stepwise calculations to measure the slope of the secant …

Before we embark on setting the groundwork for the derivative of a function, let's review some terminology and concepts. Remember that the slope of a line is defined as the quotient of the …

In mathematics, a real interval is the set of all real numbers lying between two fixed endpoints with no "gaps". Each endpoint is either a real number or positive or negative infinity, indicating the …

This is the average rate of change of the function f over the interval [x; x + h]. Taking the limit as h ! 0 gives the (instantaneous) rate of change at the point x. Example 1: The population of a …

They are made by adding and subtracting powers of x x and multiplying them by constants. These functions are continuous, which means they have no sudden jumps or breaks.

If f (x) is a function defined on an interval [a, a + h], then the amount of change of f (x) over the interval is the change in the y values of the function over that interval and is given by f (a + h) f …

A beautiful, free online scientific calculator with advanced features for evaluating percentages, fractions, exponential functions, logarithms, trigonometry, statistics, and more.

Jan 1, 2026 · You may have noticed that the open interval notation looks like the notation for a point (x, y) in the plane. It is important to read an example or a homework problem carefully to …

We say that a function is increasing on an interval if the function values increase as the input values increase within that interval. Similarly, a function is decreasing on an interval if the …
