Answer:
so density is measured in grams per cm³
but the data we have is grams and mL, but lucky for us, we can easily convert mL to cm³ but it is a bit tricky.
so you have to multiply the amount in mL by e and divide by 
which means that you have to multiply by 1, (hard,i know)
so now you know that the given liquid is 6 grams per 24 cm³
so now, we will divide the amount in grams by the volume in cm³
6/24
= 1/4 grams per cm³
This is not a function but the domain is x and the range is going to y so the first is the domain and the second box it the range
