A relation contains the points (-5, -10), (-2,-4), (-1,-2), (4,8) and (5, 10). Is this a function?
Yes, for each x, it maps into a unique y.
To determine if the given relation is a function, we need to check if each x-value is associated with exactly one y-value.
First, let's organize the given points:
(-5, -10), (-2, -4), (-1, -2), (4, 8), (5, 10)
Next, examine the x-values:
-5, -2, -1, 4, 5
Then, check if each x-value has a unique corresponding y-value:
-5 is associated with -10
-2 is associated with -4
-1 is associated with -2
4 is associated with 8
5 is associated with 10
Since each x-value is paired with exactly one y-value, this means that the relation is a function.
In summary, yes, the given relation is a function because each x-value has a unique corresponding y-value.
