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.
