The ordered pairs (1,16) (2,16) (3,32), (4,32) and (5, 48) represents the cost of buying various numbers of cds through a music club. identify the domain and range of the relation. is the relation discrete or continuous? is the relation a function?

Discrete

Step-by-step explanation:

Given are the ordered pairs as

where I ordered pair represents the no of CDs and II pair the cost of the CDs

We know that number of CDs cannot be in fraction or decimal hence this is discrete.

Domain = I ordered pair =

Range = II ordered pair =

Since each item in the domain has a unique image, we say that this relation is a function.

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~
