f(3)= 77, meaning with full time workers, the project would be complete in days. This interpretation in the context of the problem. f, left bracket, 7, right bracket, equalsf(7)= 33, meaning with 7 full time workers, the project would be complete in 33 days. This interpretation in the context of the problem. f, left bracket, 5, point, 5, right bracket, equalsf(5.5)= 42, meaning with 5.5 full time workers, the project would be complete in 42 days. This interpretation in the context of the problem. Based on the observations above, it is clear that an appropriate domain for the function is
