Find the domain and range for the relation r which contains the sets of ordered pairs (x, y) where x contains {-2, -1, 0, 1, 3, 5} and y = 2 - x.

Options:
a. Domain: {-2, -1, 0, 1, 3, 5}, Range: {0, 1, 2, 3, 4, 5}
b. Domain: {-2, -1, 0, 1, 3, 5}, Range: {1, 2, 3, 4, 5, 6}
c. Domain: {-2, -1, 0, 1, 3, 5}, Range: {-2, -1, 0, 1, 3, 5}
d. Domain: {-2, -1, 0, 1, 3, 5}, Range: {2, 1, 0, -1, -3, -5}

Final answer:

The domain of the relation r is {-2, -1, 0, 1, 3, 5}, and after calculating y = 2 - x for each x value, the range is {4, 3, 2, 1, -1, -3}. None of the provided options matches these sets exactly, possibly indicating an error in the options.

Step-by-step explanation:

To find the domain and range of the relation r, we can list out the values given for x and calculate the corresponding values for y using the equation y = 2 - x. Let's calculate the values one by one:

  • For x = -2, y = 2 - (-2) = 4
  • For x = -1, y = 2 - (-1) = 3
  • For x = 0, y = 2 - 0 = 2
  • For x = 1, y = 2 - 1 = 1
  • For x = 3, y = 2 - 3 = -1
  • For x = 5, y = 2 - 5 = -3

The domain of r is the set of all possible values of x, which in this case is given as {-2, -1, 0, 1, 3, 5}. The range of r is the set of all possible values of y that we have calculated, which is {4, 3, 2, 1, -1, -3}. To match the sets with the given options, we must order the range from greatest to smallest (or smallest to greatest), which gives us {4, 3, 2, 1, -1, -3}. However, this ordered set is not provided in the lettered options, which may indicate a typo in the provided options. The most correct answer based on our calculations would be:

Domain: {-2, -1, 0, 1, 3, 5}, Range: {4, 3, 2, 1, -1, -3}
