Work Step by Step
1. Parent function $y =f(x)=\sqrt{x}$
( Create a table with a selection of values for x,
arriving at ordered pairs (x,f(x)).
Plot them and connect with a smooth curve)
2. $y=2\sqrt{x}=2f(x)$
Stretch the graph vertically by a factor of 2.
Use the table (x,f(x)) to plot the points
$(x, 2f(x))$
and join with a smooth curve)
