# What is the range of 1 upon X?

## What is the range of 1 upon X?

Set the denominator in 1x equal to 0 to find where the expression is undefined. The domain is all values of x that make the expression defined. The range is the set of all valid y values.

**What is the domain and range of f/x )= 1 x?**

Domain is all the possible x-values that can be plugged in and range is all the possible y-values that can be outputs. f(x)=1x can have any number as an input except for zero. If we plug in zero for x , then we would be dividing by zero which is impossible. Thus the domain is all real numbers except for zero.

### How do you find the domain and range in a graph?

Another way to identify the domain and range of functions is by using graphs. Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis.

**What is the graph of 1 by X?**

So, for the function f(x) = 1/x the y-axis is a vertical asymptote, and the x-axis is a horizontal asymptote. In the following diagram of this function the asymptotes are drawn as white lines….Simple Rational Function: f(x) = 1/x.

Input value, or x | Output value, or y | |
---|---|---|

-1,000,000 | ⇒ | -0.000001 (or -1/1,000,000) |

-0.000001 (or -1/1,000,000) | ⇒ | -1,000,000 |

## What is the domain of 1?

The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined. y=1 is a straight line perpendicular to the y-axis at point (0,1) , which means that the range is a set of one value {1} .

**What is the domain of X 1 X?**

More specifically, your function 1x will be undefined for x=0 , which means that its domain will be R−{0} , or (−∞,0)∪(0,+∞) .

### What is the domain and range of 1 x 1?

Set the denominator in 1x−1 1 x – 1 equal to 0 to find where the expression is undefined. Add 1 to both sides of the equation. The domain is all values of x that make the expression defined. The range is the set of all valid y values.

**How do you graph a one to one function?**

Use the Horizontal Line Test. If no horizontal line intersects the graph of the function f in more than one point, then the function is 1 -to- 1 . A function f has an inverse f−1 (read f inverse) if and only if the function is 1 -to- 1 .
