You have 6 cups of sugar. It takes 1 cup of sugar to make 24 cookies. The function c(s) = 24s represents the number of cookies, c, that can be made with s cups of sugar.
What domain and range is reasonable for the function?
you can use from 0 to 6 s
so domain is 0 to 6
you get out from 0 to 24(6) or from 0 to 144 cookies so the range is 0 to 144
