Home / Assignment Help / 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}

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}


the numbers given in the brackets thing the {4,10,14,16,18} is the domain, the number of people possible, substitute them to find the range

f(4)=2/4=1/2=0.5
f(10)=2/10=0.2
f(14)=2/14=1/7=0.142
f(16)=2/16=1/8=0.125
f(18)=2/18=1/9=0.1111

so the time would be {0.5,0.2,0.14,0.125,0.11}
answer is D
