Square Root Functions
A square root function is a function that contains a variable under the square root symbol 
. Square and square root are inverse operations, so there will be similarities in their graphs.
Square root functions have equations in the form:
or in exponential notation as 
. Graphs of square root functions increase quickly at first then flatten to a very slow rate of change.
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).
