Which statements are true about exponential functions? check all that apply.
the domain is all real numbers.
the range always includes negative numbers.
the graph has a horizontal asymptote at x = 0.
the input to an exponential function is the exponent.
the base represents the multiplicative rate of change.

The following statements are true about exponential functions:
-The domain is all real numbers.
- The input to an exponential function is the exponent.
- The base represents the multiplicative rate of change.

The reason why the other two options are wrong are explained below:
The range of exponential functions is not always includes negative numbers; on the contrary, the range is the set of all positive real numbers.

The graph of an exponential function does not have a horizontal asymptote at x = 0; contrarily, the equation of the horizontal asymptote of the graph of is y = 0, which is the x-axis.
