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: $y = \sqrt x$

2.
For each radical function,
i) Describe the transformation(s) that should be applied to the graph of y= $y = \sqrt x$ 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.
