Square Root Functions

Domain and Range

We also need to consider the domain and range of these functions.  

Recall that:

Domain is all the possible x values for a function.  (What is the furthest left value of the function? What is the furthest right value of the function?)

Range is all the possible y values for a functions.  (What is the highest (up) value of the function? What is the lowest (down) value of the function?)
