Using the concepts of domain and range, it is found that:
- The domain of the relation is {-1, 2, 3, 4}.
- The range of the relation is {-1, 0, 2, 4}.
<h3>What are the domain and range of a relation?</h3>
- The domain of a function is the set that contains all possible input values. On a graph, it is given by the values of x.
- The range of a function is the set that contains all possible output values. On a graph, it is given by the values of y.
In this graph, the points represented are given by: {-1, 2}, {2,0}, {3,-1} and {4,4}. Hence:
- The domain of the relation is {-1, 2, 3, 4}.
- The range of the relation is {-1, 0, 2, 4}.

All these ratios people are having trouble with today.
Its pretty easy once you get the hang of it.
So they release 12 grizzly.
We can say 12/x since we dont know the amount of grizzly bears in total.
We can then set 12/x equal to 2/21 and solve for x by using cross multiplication
21/5.2
because in order to get mean you have to add all the numbers up and divide by the amount you added so 20+28+26+26+30+24+25+26+28+27= 210 divide by 10= 21
in order to get mad you take all the numbers and subtract them from the mean (what ever you get make sure the number is positive) so 21-20=1 28-21=7 and so on then add up the numbers and divide again to get 52 divide that by 10 and you get 5.2
because it is means to mad ratio the answer is 21/5.2
I think it’s the last one
62.5% of 8 is 5 so it's b
