Vocaloid:

"the store has 12 cases in stock" means that he can only buy 0-12 cases, so your domain is whole numbers from 0 to 12 using this information, calculate the value of f(c) at each of the domain values and put these values together in a set as the range

Pixel:

Can you help with that please?

Vocaloid:

f(c) = 24c + 5 for c = 0, f(c) = 24(0) + 5 = 5 for c = 1, f(c) = 24(1) + 5 = 29 and so on and so forth for c = 0 to c = 12

the domain is whole numbers from c = 0 to c = 12, so domain = {0,1,2,3,4,5,6,7,8,9,10,11,12} the range is just the list of output values for each of these domain values

Vocaloid:

f(c) = 24c + 5 so you start by plugging in c = 0 to get f(c) = 5 (the first range value) c = 1 gives f(c) = 29 (the second range value) then keep going for all the domain values
