Basic radical functions

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.


  • 1.
    Basic Radical Function: y=xy = \sqrt x
  • 2.
    For each radical function,
    i) Describe the transformation(s) that should be applied to the graph of y= y=xy = \sqrt x in order to obtain the graph of the given radical function.
    ii) Write the "Coordinate Mapping Formula", then sketch the graph.
    iii) State the domain and range.
