see explanation.

#### Explanation:

to sketch f(x) =

choose appropriate values for x and substitute them into the function to obtain corresponding value of y. Then plot these coordinate points on squared paper.

Now you can plot the points (0 ,1 ) , (1 , 3 ) , (2 , 9 ) and (3 , 27 )

There are also negative values of x that can be considered.

Here make use of the fact that

Now you can plot the points

I have included the graph of
