## How do you solve a square root function?

To Solve a Radical Equation:

- Isolate the radical on one side of the equation.
- Square both sides of the equation.
- Solve the new equation.
- Check the answer. Some solutions obtained may not work in the original equation.

### What are square root graphs called?

A 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. An example of a radical function would be. y=√x. This is the parent square root function and its graph looks like.

#### What is the purpose of square root functions?

(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.

**What are the characteristics of a square root function?**

Basic square root function takes the square root of independent quantity. 2. Domain and range of a basic square root function are restricted, because the square root of a negative number does not exist. Both domain and range of the basic function are from zero to infinity.

**What are the key features of a square root function?**

## What are square root functions used for in real life?

Square roots are used in finance (rates of return over 2 years), normal distributions (probability density functions), lengths & distances (Pythagorean Theorem), quadratic formula (height of falling objects), radius of circles, simple harmonic motion (pendulums & springs), and standard deviation.

### How do you move a square root down a graph?

The value of h shifts the graph horizontally. If h is positive, the graph shifts to the right and if h is negative, the graph shifts to the left. The value of k shifts the graph vertically. If k>0 then the graph shifts up and if k<0 then the graph shifts down.
