###### Lessons
1. Describe the transformation(s) that should be applied to the graph of $y = \sqrt x$ in order to obtain the graph of the given radical function.
1. $y - 2 = \sqrt {x + 3}$
2. $y = \sqrt { - x}$
3. $- y = \sqrt x$
4. $\frac{1}{3}y = \sqrt {2x}$
5. $y = - 2\sqrt {\frac{x}{3} - 1} + 5$
Radical functions: a function which contains a variable inside a root. For example: $y = \sqrt x$ , $y = {^3}\sqrt{{x - 5}}$
$y = 2{^4}\sqrt{{3x - 8}} + 11$
