3.3 - Square Root Functions

Author: Kyle Webb
  • Graph square root functions without a table of values and later confirm with at least three points from a table of values.
  • Find the domain and range of square root functions
  • Graph inequalities of square root functions using knowledge gained from graphing square root functions.

This packet will introduce square root functions and how they are graphically represented.

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?)
