What will happen if we put a square root in a function? What will its graph look like? We will tackle these questions in this lesson and see it yourself!

- 1.
**Comparing: $y = f\left( x \right)$ VS. $y = \sqrt {f\left( x \right)}$**

Given $f\left( x \right) = x + 3$,a)b)State the domain and range of each function.

- 2.
**Graphing $y=\sqrt{f(x)}$ from the Graph of $y=f(x)$**

Given the graph of $y = f\left( x \right)$ as shown:

a)Sketch the graph of $y = \sqrt {f\left( x \right)}$ .b)State the domain and range of:

i) $y = f\left( x \right)$

ii) $y = \sqrt {f\left( x \right)}$
