f%28x%29=3%5Ex 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

f%28-2%29=3%5E-2 Plug in x=-2

f%28-2%29=0.111111111111111 Raise 3 to the negative second power to get 0.111111111111111

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


----Now lets find another point----
f%28-1%29=3%5E-1 Plug in x=-1

f%28-1%29=0.333333333333333 Raise 3 to the negative first power to get 0.333333333333333

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


----Now lets find another point----
f%280%29=3%5E0 Plug in x=0

f%280%29=1 Raise 3 to the zeroth power to get 1

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


----Now lets find another point----
f%281%29=3%5E1 Plug in x=1

f%281%29=3 Raise 3 to the first power to get 3

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


----Now lets find another point----
f%282%29=3%5E2 Plug in x=2

f%282%29=9 Raise 3 to the second power to get 9

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

Now lets make a table of the values we have calculated

Now plot the points



Connect the points to form the graph y=3%5Ex
