Question

The number of hours required to do a painting job is represented by the function , where f(x) gives the number of hours and x is the number of painters doing the job. How much time will {4, 10, 14, 16, 18} workers take to do the job?

Answer 1

You need to provide the function.

Your question is very simple. You simply take those numbers they gave you and replace it with x and solve for f(x). That will tell you how many hours it takes for x workers to paint.
