# How do you solve a square root function?

## How do you solve a square root function?

1. Isolate the radical on one side of the equation.
2. Square both sides of the equation.
3. Solve the new equation.
4. 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.
