Answer: The range of the function f(x) = 3^x is all positive real numbers, excluding zero.
Step-by-step explanation:
Since 3^x will always be positive for any real value of x, the function does not have any negative values in its range. Additionally, as x approaches negative infinity, 3^x will approach zero, but it will never actually reach zero. Therefore, the range of the function is all positive real numbers, excluding zero. In interval notation, the range can be represented as (0, +∞).
