Natural Exponential Function

In technical and financial modeling, an exponential function is defined as $f(x) = a^x$ (where $a > 0$ and $a eq 1$). What is the domain of this function, representing the set of all possible real numbers that can be substituted for the exponent $x$?

Domain of Exponential Growth Models

In professional data modeling, an analyst uses the exponential function $f(x) = a^x$ to project company growth. True or False: The domain of this function is restricted to positive values of $x$ because negative exponents are undefined in this model.

A logistics coordinator uses the exponential function $f(x) = a^x$ to forecast supply chain growth over time. Because there are no mathematical restrictions on the values that can be substituted for the exponent $x$, the domain of this function consists of all real numbers. In interval notation, this domain is written as ____.
