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.

For an exponential function such as f(x) = b^x, any real number can be used as the input, so its domain is all real numbers. The input x is the exponent, and the base b gives the multiplicative rate of change. The function’s outputs are positive, and its horizontal asymptote is y = 0, not x = 0; therefore B and C are false.
