Question

What is the range of the following set of
points (3.4), (7-2). (11-8))?

Answer 1

The range of the following set of points is {4, -2, -8}

Explanation:

• The domain of a set of ordered pairs is the values of x-coordinates of all ordered pairs

• The range of a set of ordered pairs is the values of y-coordinates of all ordered pairs

• Ex: In the set of points {(1, 3), (-4, 5), (2, -5)} the domain is {1, -4, 2} and the range is {3, 5, -5}

∵ The set of points is {(3, 4), (7, -2), (11, -8)}

∵ The range is the y-coordinates of these points

∵ The y-coordinates of the points are 4, -2, -8

∴ The range is {4, -2, -8}

∴ The range of the following set of points is {4, -2, -8}
