  1. Introduction to Radical Functions
    • What is a radical function?
    • A radical functions is a function which contains a variable inside a root, for example: y=xy = \sqrt x , y=3x5y = {^3}\sqrt{{x - 5}}, y=243x8+11y = 2{^4}\sqrt{{3x - 8}} + 11
  1. Basic Radical Function: y=xy = \sqrt x
    1. Use a table of values, sketch the graph of the function y=xy = \sqrt x .
    2. State the domain and range.
Topic Notes
A radical function is a function that contains a variable inside a root. By graphing out a radical function, we can easily find out its domain and range.
