# What Is The Domain Of The Square Root Function Graphed Below?

The domain of a function is the set of all possible inputs that are accepted by the function. The square root function is one such function that has a specific domain, which can be determined by graphing the function. In this article, we will discuss what the domain of the square root function is and how it can be determined by graphing the function.

## Overview of Square Root Function

The square root function is a type of unary operation that takes a single input and produces an output. The output is the square root of the input. The square root of a number is the number that, when multiplied by itself, gives the original number. For example, the square root of 9 is 3, because 3 multiplied by 3 is 9.

This function can be represented by the equation y=√x. Here, x is the input and y is the output. The domain of the square root function is the set of all real numbers greater than zero. This means that the square root of any number less than or equal to zero is undefined.

## Graphing the Square Root Function

The domain of the square root function can be determined by graphing the function. To graph the square root function, we can use the x- and y-axes to represent the input and output, respectively.

The square root function is a continuous function, meaning that it has no breaks or jumps. When graphing the function, we will draw a smooth curve that follows the equation y=√x. The graph will look like a curved line that starts at the origin (0,0) and goes up in a curved fashion.

The domain of the square root function is all real numbers greater than zero. This means that the graph will only include points to the right of the origin. Any points to the left of the origin will not be included in the graph.

In conclusion, the domain of the square root function is the set of all real numbers greater than zero. This can be determined by graphing the function. The graph of the square root function is a continuous curve that starts at the origin and only includes points to the right of the origin. Understanding the domain of the square root function is important for solving equations involving the square root function.
