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: $y = \sqrt x$ , $y = {^3}\sqrt{{x - 5}}$

$y = 2{^4}\sqrt{{3x - 8}} + 11$

$y = 2{^4}\sqrt{{3x - 8}} + 11$
