The population of wild horses on a wildlife refuge decreased from 110 to 99 in a year. If this trend were to continue, what exponential equation could be used to predict the horse population in the future?

y = 110 (1.1) ^x

y = 99 (0.9) ^x

y = 99 (1.1) ^x

y = 110 (0.9) ^x,

The exponential equation for this situation is y = 110 (0.9) ^x. This is because 110 is the principal or the initial number of horses and y is the resultant population after a certain number of years X with a rate of 0.9. Note that the rate is less than 1 which means that the population is decreasing as time goes by.
