Answer:

y = -3e^x

Explanation:

If the horizontal asymptote is y=0 and the range is negative, then the parent exponential function is reflected across the x-axis. It will have a coefficient of -3 in order to make the y-intercept be -3. The base of the exponent can be any positive number not equal to 1. One possibility is ...

y = -3e^x
