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.

5.25 ounces

step-by-step explanation:

divided 3/4 and 6

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
