I'm having issues with this math problem I will upload a photo

We have
[tex]f(x)=4^{x-1}[/tex]First, we will graph the function with some points
x f(x)
-5 0.00024
0 0.25
1 1
2 4
3 16
So the graph will be the next one
The domain is the set of all possible values that x can have in this case the domain is
[tex]\: \mleft(-\infty\: ,\: \infty\: \mright)[/tex]The range is the set of all possible values that y can have in this case the range is
[tex]\: \mleft(0,\: \infty\: \mright)[/tex]
