Question

What is the range of the inverse of relation {(1, 7), (2, -4), (5, 6), (2, 8)}?
A. {1, 2, 5}
B. {-4, 6, 7, 8}
C. {1, 5}
D. {-4, 7, 8}

Answer 1

{(1, 7), (2, -4), (5, 6), (2, 8)}
--------------------------

The domain is the set of x-values of these points.
The range is the set of y-values of these points.

Answer 2

In general terms, the inverse of this relation would reverse the x and y coordinates of a given point.

So, under the inverse, the point (1, 7) would become (7,1).

Then, the range of the relation would have 1 in it.

Answer 3

So A would br the answer ?

Answer 4

{(1, 7), (2, -4), (5, 6), (2, 8)}

Inverse: { (7,1); (-4,2); (6,5), (8,2)} --What is the range of this set, @mathhelp16 ?

Answer 5

>So A would br the answer Yes.

Answer 6

In general terms, the range of the inverse of a relation turns out to be the domain of the original relation.
