Question

A population of 59 foxes in a wildlife preserve quadruplets in size every year. The function, y=59•4x where x is the number of years models of the population growth. Using the given function how many foxes will there be after 5 years?

Answer 1

A student was trying to write an exponential function to represent a fish population in a local stream decreasing at a rate of 4% per year. The original population was 48,000. The student made an error when writing their exponential function find and explain the error in the students work below
y=48,000(1.04)^x
