An equation with an exponent of the form 1/x is not an exponential equation -- either growth or decay.

ANSWER: neither

the equation is y = 16.5 * (1.025) ^ (1/x)

i don't believe this is an exponential function.

here's what i found as a definition of an exponential function.

The domain of exponential functions is all real numbers. The range is all real numbers greater than zero. The line y = 0 is a horizontal asymptote for all exponential functions. When a > 1: as x increases, the exponential function increases, and as x decreases, the function decreases.

since your exponent is 1/x, then the domain is not all real values of x, since there is a discontinuity at x = 0.
