The function is $\"\"$ .

Basic function is $\"\"$ .

Square root function is defined only positive $\"\"$ -values.

The graph of $\"\"$ is obtained from $\"\"$ , multiplying each $\"\"$ -coordinate of $\"\"$ by $\"\"$ .

Choose random values for $\"\"$ and find the corresponding values for $\"\"$ .

\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \

Graph:

Draw a coordinate plane.

Plot the points of the basic function $\"\"$ and connect these points with smooth curve.

Plot the points of the $\"\"$ are $\"\"$ and connect these points with smooth curve.

$\"\"$

Observe the graph:

The graph of $\"\"$ is identical to $\"\"$ except that it is stretch the graph vertically, multiplying each $\"\"$ -coordinate of $\"\"$ by $\"\"$ .

The domain of the $\"\"$ is $\"\"$ .

Domain of $\"\"$ in the interval notation: $\"\"$ .

Range of $\"\"$ is $\"\"$ .

Range of $\"\"$ in the interval notation: $\"\"$ .
