i suck at domain and range.... this doesn't make any sense...
a. Given the relation {(-3,-2)(-1,0)(2,-1)(3,5)}, explain why the domain would NOT be -3 <or less than x <or less than 3(-3 <_ x <_ 3) and similarly the range would NOT be -2 <or less than y <or less than 5(-2 <_ y <_ -5).
b. What shouuld the domain and range be?
Domain:?
Range:?
lol theyre still waiting for the answer
Fourteen years later..... still don't have the answer.
Watch, arya didn't graduate just because she couldn't answer this lol.
a. To determine the domain of a relation, you need to consider all the x-values (inputs) that appear in the relation. In this case, the x-values are -3, -1, 2, and 3. When we list the x-values in ascending order, we get -3, -1, 2, 3.
Given that, we might think that the domain would be -3 ≤ x ≤ 3. However, in this relation, we can see that the x-values are not consecutive or continuous. There is a gap between -1 and 2. So, the domain is not a continuous range of numbers but rather a set of individual values.
Similarly, when we consider the range, we need to look at the y-values (outputs). The y-values in this relation are -2, 0, -1, and 5. When we list the y-values in ascending order, we get -2, -1, 0, 5.
Again, we might think that the range would be -2 ≤ y ≤ 5. However, similar to the x-values, the y-values are not consecutive or continuous. There is a gap between 0 and -1. So, the range is also not a continuous range of numbers but a set of individual values.
b. The domain of this relation would be the set of x-values, which is {-3, -1, 2, 3}. Each of these numbers represents an individual point in the relation.
The range of this relation would be the set of y-values, which is {-2, -1, 0, 5}. Again, each of these numbers represents an individual point in the relation.
Therefore, the domain for this relation is {-3, -1, 2, 3} and the range is {-2, -1, 0, 5}.
