an exponential growth function has an asymptote of y = -3. which might have occurred in the original…

Brief Explanations:

The general form of an exponential function is $y = a\cdot b^{x}+k$, where $y = k$ is the horizontal - asymptote. For the range to include negative numbers and have an asymptote of $y=-3$, a constant is added or subtracted to the whole exponential expression. Adding or subtracting a constant to/from the exponent only shifts the function horizontally and does not change the range in terms of allowing negative values when the basic exponential function $y = b^{x}>0$. If we add or subtract a constant to the exponential expression $b^{x}$, we can change the vertical position of the function relative to the x - axis.

Answer:

A whole number constant could have been added to the exponential expression.
