The domain of the function you have submitted is the whole real line (-∞,∞) and it is independent of a.

ax - 15 is continuous on the whole real line.

If perchance you meant ax

^{-15}, the answer is the whole real line except for x = 0.Paul M.

Then the domain would be x greater than or equal to 15/a since if x were less than that the expression under the radical would be negative (assuming you are considering only real-valued functions).
