Use the given function and domain to find the range. f(x)=1/3x+4

The range is {2, 4, 7}.

I got this by inputting each of the domain numbers into the given function as shown:

F(6)=1/3(2)+4
F(0)=1/3(0)+4
F(9)=1/3(9)+4

x is replaced by the numbers in the domain, including the f(x) part.  In any case, when you solve the problems above, the results are 2, 4, and 7 -- which constitutes the range of the function, or the set of all possible outputs.  The domain constitutes the set of all possible inputs for the function.  

Yes, two vertical lines can be complementary

1.5 pounds because you put 9over 6 and then divide by 6
