$\"\"$

The function is $\"\"$ .

Find the value of $\"\"$ .

Draw a table:

Consider different values of $\"\"$ to find the corresponding values of $\"\"$ .

$\"\"$

Graph:

Graph the function $\"\"$ and plot the coordinates.

$\"The$

Observe the graph:

The graph crosses the $\"\"$ axis at $\"\"$ , so the $\"\"$ -intercept is $\"\"$ .

The domain is all real numbers and the range is all real numbers greater than zero. $\"\"$

Use the graph to approximate the value of $\"\"$ .

The graph represents all real values of $\"\"$ for $\"\"$ .

When $\"\"$ , the value of $\"\"$ is about $\"\"$ .

Use a calculator to confirm this value: $\"\"$ .

$\"\"$

Graph of the function $\"\"$ is

$\"The$

The $\"\"$ -intercept is $\"\"$ .

The domain is all real numbers and the range is all real numbers greater than zero.

The value of $\"\"$ is $\"\"$ .
