Question

SOMEONE PLEASE HELP?? MEDAL:D
What is the range of the following relation?

A. {-3,1,2}
B. {-4,-3,-1,1,3}
C. {-3,-1,1,2}
D. {-4, 1,2}

Answer 1

The range is the collection of all the y's, or the second value in the ordered pair.

Answer 2

so would it be B than?

Answer 3

@jim_thompson5910 please help with this one?

Answer 4

Example:

The points (1,2) and (4,7) have the y coordinates of 2 and 7 respectively.

Therefore, the range of those set of points (think of them collectively as a function) is the set {2, 7}

Answer 5

basically, range is just the set of y values

Answer 6

so the answer would be B

Answer 7

ya so our answer would be b right?

Answer 8

is -4 a y coordinate of any of the points?

Answer 9

oh s that would make it D then huh?

Answer 10

is -4 a y coordinate of any of the points?

yes? or no?

Answer 11

sorry i miss read the graph worry, my apologizes

Answer 12

no

Answer 13

so b can't possibly be the answer because of that -4

Answer 14

the range will be some set of numbers, but we know for sure that -4 won't be in that set

Answer 15

I think its A

Answer 16

the answer would be -3 ,-1,1,2

Answer 17

Nope C sorry

Answer 18

ok better, but not quite the answer

the set in choice A has all the right numbers BUT it's missing one y value

Answer 19

good, it's C

Answer 20

the y coordinates of the points are -3,-1,1, and 2

so the range is {-3,-1,1,2}
