How to Find a Horizontal Asymptote of an Exponential Function:

        If the exponential function is y = abx then the horizontal asymptote of the given exponential function is y = 0

        If the exponential function is y = abx + c then the horizontal asymptote of the exponential function is y = c

        If the exponential function is y = abx - c then the horizontal asymptote of the exponential function is y = -c
