Jeff writes comic strips for a local newspaper. The number of comic strips he creates is represented by the function f(x) = 3x, where f(x) gives the number of comic strips and x is the number of work hours he puts in, which varies day to day. If he puts in {3, 4, 6, 7, 9} work hours, how many comic strips can he write?

anonymous · Answer

okay so basically all you are doing is plugging each number in. I will do one of them.
f(9) = 3(9) 3 * 9 = 27 So, when he works 9 hours he can make 27 comic strips.

The number of hours required to do a painting job is represented by the function f(x)=2x , 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?

It's the same idea as the comic strip one just plug in the numbers.
