The number of hours required to do a painting job is represented by the function f(x)=2/x, 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?
a.{1.0, 0.9, 0.8, 0.7 0.2}
b.{0.9, 0.8, 0.6, 0.4, 0.1}
c.{0.9, 0.84, 0.73, 0.59, 0.2}
d.{0.5. 0.2, 0.14, 0.125, 0.11}
