Answer

Final Answer: The range of the given exponential function is \(\boxed{(0, \infty)}\).

Steps

Step 1 :The given function is \(2^{x}-1\).

Step 2 :The range of an exponential function of the form \(f(x) = a^x\) where \(a > 0\) and \(a \neq 1\) is \((-\infty, \infty)\).

Step 3 :However, in this case, the function is shifted down by 1 unit.

Step 4 :So the range should be \((1 - 1, \infty) = (0, \infty)\).

Step 5 :Final Answer: The range of the given exponential function is \(\boxed{(0, \infty)}\).
