State the Domain and Range: { (-1,1) (-3,3) (5,-5) (-7,7)

d = {-1, -3, -5, -7}

range { 1,3,5,7}

range = {-5, 1, 3, 7}

d = { -7, -3, -1, 5}

To determine the domain and range from the given set of points, we analyze the pairs:

The given set of points is: { (-1, 1), (-3, 3), (5, -5), (-7, 7) }

Domain:

The domain is the set of all first elements (x-values) from the ordered pairs.

From the points:

  • The x-values are: -1, -3, 5, -7

So, the domain is: Domain: { -7, -3, -1, 5 }

Range:

The range is the set of all second elements (y-values) from the ordered pairs.

From the points:

  • The y-values are: 1, 3, -5, 7

So, the range is: Range: { -5, 1, 3, 7 }

To summarize:

  • Domain: { -7, -3, -1, 5 }
  • Range: { -5, 1, 3, 7 }
