Considering the relation {(elephant, 25), (reindeer, 32), (greyhound, 39), (elk, 45)}, we have that:
- The domain is: {elephant, reindeer, greyhound, elk}.
- The range is: {25, 32, 39, 45}.
<h3>What are the domain and the range of a function?</h3>
- The domain of a function is the set that contains all the values of the input.
- The range of a function is the set that contains all the values of the output.
In this problem, the relation is given as follows:
Hence, the relation is {(elephant, 25), (reindeer, 32), (greyhound, 39), (elk, 45)}, and the domain and range are given as follows:
- The domain is: {elephant, reindeer, greyhound, elk}.
- The range is: {25, 32, 39, 45}.

Let x represent the width of the garden(s). Then the length of the second garden is (3x+3). The area is the product of length and width,
90 = x(3x+3)
30 = x(x+1)
At this point, you can recognize that 5 and 6 are factors of 30 that will satisfy this equation, or you can solve the quadratic
x² +x -30 = 0
(x +6)(x -5) = 0
x = 5 . . . . . . . the negative solution does not apply
The width of the garden is 5 m.
