Final answer:
Yes, the domain of an exponential function encompasses all real numbers.
Step-by-step explanation:
Yes, the domain of an exponential function encompasses all real numbers.
An exponential function is a function of the form f(x) = a^x, where a is a positive constant called the base. Since the exponent can take on any real number, the domain of an exponential function is all real numbers.
For example, the function f(x) = 2^x has the domain of all real numbers, and any real number can be plugged in for x.
