The table represents the exponential function:
Here we have the table:
x y
-1 1/11
0 1
1 11
2 121
3 1331
Some things that are useful to identify this as an exponential equation are:
For any real number a different than zero:
With these three things, we conclude that we have an exponential equation, because when we evaluate in x = -1, we have a rational number.
When we evaluate in x = 0 we have 1.
Such that the function is:
Notice that:
And so on.
