Square root of a function
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 $f\left( x \right) = x + 3$, 
2.
Graphing $y=\sqrt{f(x)}$ from the Graph of $y=f(x)$
Given the graph of $y = f\left( x \right)$ as shown:
