f(x)=3^(x-2)+1

This makes sense to me that the domain is all Real numbers.

When I graph this function the range tells me that it is y≥ 1

To make this easy for me I set:

y=3^(x-2)+1

Subtract 1

y-1=3^(x-2)

This is where I’m stuck..do I divide by the 3? Or do I need to do Logbase ..steps would help me out a lot. Thank you.
