James can store 8 GB of music on his phone. If a 3-min digital song requires 3.5 MB of storage space, what are the domain and range for the relationship between memory used and number of songs that are each 3 min in length?

Assuming 1GB = 1000MB then possible storage = 8000/3.5 ≈ 2285.7 songs.  However, storage for complete songs is just 2285, which requires 2285*3.5 = 7997.5 MB

 

So domain (number of songs):  0 to 2285

 

Range (memory): 0 to 7997.5 MB

 

(NB memory = 3.5*nbr of songs)
