Answer :
Try to determine the value when they all add up. Or If you’re working with fractions try cross canceling
Step-by-step explanation:
given : (2,7). (8, 12). (5,9). (10.15)
domain: will always be the first value of numbers ; 2, 8, 5, 10
range: will always be the second value of numbers ; 7, 12, 9, 15
what you have here is :
Domain: (2,5, 7, 8, 10)
Range: (7.9. 10. 12. 15)
what's wrong is 7 is in the domain, and 10 is in the range. those two don't belong there. theres also a extra number you have in there. domain and range should only have 4 numbers. since there is four pairs/set of values
