asked in category: General Last Updated: 7th June, 2020# Are Radical Equations functions?

**radical function**contains a

**radical**expression with the independent variable (usually x) in the radicand. Usually

**radical equations**where the

**radical**is a square root is called square root

**functions**. The value of b tells us where the domain of the

**radical function**begins.

Similarly, it is asked, can a function have a radical?

A **radical function** is a **function** that contains a square root. **Radical functions** are one of the few types of **functions** that require you to consider the domain of the **function** before you graph the **function**.

Furthermore, how do you define a radical? In mathematics, a **radical** expression is defined as any expression containing a **radical** (√) symbol. Many people mistakenly call this a 'square root' symbol, and many times it is used to determine the square root of a number. However, it can also be used to describe a cube root, a fourth root, or higher.

Similarly, you may ask, what are Radical Equations used for?

Both have real world applications in fields like architecture, carpentry and masonry. **Radical** expressions are utilized in financial industries to calculate formulas for depreciation, home inflation and interest. Electrical engineers also **use radical** expressions for measurements and calculations.

Is square root a function?

The principal **square root function** f(x) = √x (usually just referred to as the "**square root function**") is a **function** that maps the set of nonnegative real numbers onto itself. In geometrical terms, the **square root function** maps the area of a **square** to its side length.
