Question

In the properties of an exponential function, what is the domain?

1) All real numbers
2) All positive real numbers
3) All negative real numbers
4) All non-zero real numbers

Answer 1

Main Answer:

The domain of an exponential function is typically all real numbers, so option 1) All real numbers is correct.

Step-by-step explanation:

An exponential function is defined for all real numbers as it can take any real number as an exponent.

The general form of an exponential function is
`\(f(x) = a^x\)`, where
`\(a\)` is a positive constant and
`\(x\)` can be any real number.

Therefore, the correct domain for an exponential function is option 1) All real numbers.
