Answer:
The given funciton is
[tex]y=a^{b}[/tex]
This is an exponential function, where [tex]a>0[/tex] and [tex]b \in R[/tex]. Remember that the range of an exponential function can't be negative or zero, because all powers can only be more or equal than 1.
Therefore, the graph of an exponential is like the image attached (it shows an example of an exponential function), where you can observe the range restriction.
