Find the range of the exponential function. Write the range using interval notation.

Step 1 ：Find the range of the exponential function. Write the range using interval notation.

Step 2 ：The range of an exponential function is the set of all possible output values (y-values) that we can get by substituting the domain values (x-values) into the function.

Step 3 ：For an exponential function of the form \(f(x) = a * b^x\), where a and b are positive real numbers and b ≠ 1, the range is always (0, ∞) in interval notation.

Step 4 ：This is because the exponential function is always positive and can take any positive value, but it never reaches 0.

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