Graph:
\Graph the function and plot the coordinates.
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: .
