Question

Anthony was tracking the increasing number of animals in the zoo. At 9 a.m. there were 56 animals. At 11 a.m. there were 60 animals. If Anthony made the function f(x) = 2x − 38, what would the 2 represent?

Answer 1

The rate at which the number of animals was increasing

The length of time he recorded for
