## What Is A Reciprocal Function?

Reciprocal functions are **functions that have a constant on their denominator and a polynomial on their denominator**. The reciprocal of a function can be determined by finding the expression for 1 f ( x ) . We can graph a reciprocal function using the function’s table of values and transforming the graph of y = 1 x .

## What is the basic reciprocal function?

**r(x) = a / (x – h) + k**.

## Why is it called a reciprocal function?

The parent graph for some rational functions is begin{align*}y=frac{1}{x}end{align*}. Below we have a table of values for this function. **Notice that the y-values are reciprocals of the x-values**. Hence this function is called the reciprocal function.

## What is reciprocal function graph?

**form y=**where k is any real number. Their graphs have a line of symmetry as well as a horizontal and vertical asymptote. The key to graphing reciprocal functions is to familiarize yourself with the parent function y=

^{k}/_{x}^{k}/

_{x}.

## How do you find the equation of a reciprocal function?

**y=kx y = k x**where k is any real number and x can be a variable number or a polynomial.

## How do you find a reciprocal?

**just calculate “1 ÷ (that number)**.” For a fraction the reciprocal is just a different fraction with the numbers “flipped” upside down (inverted). For instance the reciprocal of

^{3}/

_{4}is

^{4}/

_{3}. Any number times its reciprocal will give you 1.

## What does reciprocal look like?

A reciprocal or multiplicative inverse is **simply one of a pair of numbers that when multiplied together equal 1**. … For example the reciprocal of 2/3 is 3/2 (or 1-1/2) because 2/3 x 3/2 = 1. The reciprocal of 7 is 1/7 because 7 x 1/7 = 1.
