Math Problem Statement

Which of the following is the inverse of {(-2, 3), (7, -10), (2, -3), (-7, 10)}?

Solution

To determine the inverse of a set of ordered pairs, such as {(2,3),(7,10),(2,3),(7,10)}\{(-2, 3), (7, -10), (2, -3), (-7, 10)\}, we need to swap the components in each pair.

Let's compute the inverse by swapping the elements of each pair:

  1. Swap (2,3)(-2, 3) to (3,2)(3, -2),
  2. Swap (7,10)(7, -10) to (10,7)(-10, 7),
  3. Swap (2,3)(2, -3) to (3,2)(-3, 2),
  4. Swap (7,10)(-7, 10) to (10,7)(10, -7).

Thus, the inverse is: {(3,2),(10,7),(3,2),(10,7)}.\{(3, -2), (-10, 7), (-3, 2), (10, -7)\}.

The correct answer is the first option: {(3,2),(10,7),(3,2),(10,7)}.\{(3, -2), (-10, 7), (-3, 2), (10, -7)\}.

Tip: The inverse of a relation swaps the input and output, just like reflecting a graph across the line y=xy = x.
