Now Playing:Square root of a function – Example 1a

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

f\left( x \right) = x + 3

Use a table of values, graph the functions

y = f\left( x \right)

and

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

Graphing $y=\sqrt{f(x)}$ from the Graph of $y=f(x)$
Given the graph of $y = f\left( x \right)$ as shown:
1. Sketch the graph of $y = \sqrt {f\left( x \right)}$ .
2. State the domain and range of:
  i) $y = f\left( x \right)$
  ii) $y = \sqrt {f\left( x \right)}$
