Domain of the following function...?

When graphed: 2.1(0.75)^x the graphed picture never goes below the y-axis so that means that 0 is greater than or equal to y (that is the range). Now, for the domain, what would it be?

All x-values are in the domain so it's (-infinity,infinity).

The range is (0,infinity) like you correctly stated.
