Start with the given expression
In order to plot an exponential function, we need to plot some points
We can start at any x value, so lets start at x=-2

Plug in

Raise 3 to the negative second power to get 0.111111111111111

So when , . So our first point is (-2,0.111111111111111)

----Now lets find another point----
Plug in

Raise 3 to the negative first power to get 0.333333333333333

So when , . So our second point is (-1,0.333333333333333)

----Now lets find another point----
Plug in

Raise 3 to the zeroth power to get 1

So when , . So our third point is (0,1)

----Now lets find another point----
Plug in

Raise 3 to the first power to get 3

So when , . So our fourth point is (1,3)

----Now lets find another point----
Plug in

Raise 3 to the second power to get 9

So when , . So our fifth point is (2,9)

===============================================================================

Now lets make a table of the values we have calculated



 x y

 -2 0.111111111111111 
 -1 0.333333333333333 
 0 1 
 1 3 
 2 9

Now plot the points

Connect the points to form the graph
Graph of through the points solved for earlier
