Square Root Functions
A square root function is a function that contains a variable under the square root symbol![SqRt1-1 SqRt1-1](https://claregladwinresd.glk12.org/pluginfile.php/893/mod_book/chapter/42/Families_Of_Functions/Images/SqRt1-1.png)
Square root functions have equations in the form:
![SqRt1-2 SqRt1-2](https://claregladwinresd.glk12.org/pluginfile.php/893/mod_book/chapter/42/Families_Of_Functions/Images/SqRt1-2.png)
![SqRt1-3 SqRt1-3](https://claregladwinresd.glk12.org/pluginfile.php/893/mod_book/chapter/42/Families_Of_Functions/Images/SqRt1-3.png)
See the table and graph of a basic square root function below.

Here are some situations that can be modeled by square root functions:
- Power factor and electrical load distribution (power vs. load).
- Collision detection for polygon shaped objects (direction vs. size).
- Fly ball behind the plate (distance vs. time).
