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}.

Answer:
x > 3
Step-by-step explanation:
In equalities such as this one we need something that has a higher value tha eight.
2 * 4 = 8 so that too low, therefore x would have to be bigger than 2.
Lets call your age x and your sisters would be x +2
x + x + 2 = 32
combine like terms
2x + 2 = 32
32 - 2 = 2x
32 - 2 = 30
2x = 30
x = 15
Your age is 15 and your sisters is 17

The answer is that one of the numbers is 24 and the other is 50. Let's call the smaller number x, since the larger number is based on info provided for the smaller. So smaller number is x. The larger number is 3x-22, since it is 22 less than (subtraction) 3times (multiplication) the number, x. So add 2x (two times a smaller number) and 3x-22 together and set them equal to 98: 3x - 22 + 2x = 98. Simplify to get 5x = 98, divide to get that x = 24. Now put that x into the other equation for the larger number: 3(24)-22=50
