3,4
3,2
3,0

Answers: (4,3) is an Ordered Pair.

2 is an x-coordinate.

There are 5 elements in the domain.

The Range is {0,2,4,5}

Answer 1

in order to learn from this question you must know all the terminology being used.
is (4, 3 ) an ordered pair in the relation?

Answer 2

do you see any pair that is 4,3? no. only 3,4 which is not the same thing. so that is not it. do we see anything that has 2,?. no, only 3,2 and that 2 is the y coordinate. the domain is another way of saying"X" -how many diff numbers do we have/(0,1,3) thats only3! the range is another way of saying "Y". what y numbers do we have (0,2,4,5) . so the correct answer is the last statement

Answer 3

oh........... So the answer would be 5 elements in the domain?

Answer 4

They want you to memorize that the x values (first number in the pair) is called the domain, and the y values are called the range.

Answer 5

oh.......... OOOOOOOHHHHH! I see what you did there. Now I get it.

Answer 6

5 different numbers?? in the domain

Answer 7

no, there are not 5 diff numbers in the x values.(only 3) but there are the follwoing numbers for the y values:0,2,4,5
