Transformations of radical functions

It is always so much easier to tell the domain and range of a function from its graph. In this lesson, we will learn how to graph out a radical function by using a table of value and transformations.


Radical functions: 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

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