Now, graph the function.

Plot two points to graph the function.

solution

First, complete the table. Plug the

-values

into the function

For example, this shows how to plug in

Find the rest of the missing values in the same way. Remember that

–

and

for any nonzero real number

x	y
– 1	1 8
0	1
1	8
2	64

Next, use two ordered pairs from the table to graph the function

For example, you can plot

(

)

and

(

)

Here is the graph of

As the value of

increases, the function increases rapidly. As the value of

decreases, the function approaches the

-axis

but never reaches it.
