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!
Lessons

1.
Compare graphs of $y = f\left( x \right)$ and $y = \sqrt {f\left( x \right)}$
Given $f\left( x \right) = x + 3$, 
2.
Given the graph of $y = f\left( x \right)$ as shown:

b)
State the domain and range of:
i) $y = f\left( x \right)$
ii) $y = \sqrt {f\left( x \right)}$
