Question

Which of the following ordered pairs could be in a relation that has a range of {2, 4, 5}?

a) (2, 3), (4, 1), (5, 2)
b) (5, 3), (5, 4), (5, 2)
c) (4, 3), (5, 5), (5, 2)
d) (3, 4), (5, 5), (5, 2)

Answer 1

Choice D is the correct one

Explanation:

The range of a function simply refers to the possible values the function can assume, that is the set of values that y can take. In the fourth relation, the y-coordinates are 4,5,2

Answer 2

d) (3, 4), (5, 5), (5, 2)

Explanation:

We are asked to determine which orderpair in the option has the range of {2,4,5}

Using the definition of range:

The range of a function is the complete set of all possible resulting values of the dependent variable (y, usually), after we have substituted the domain.

So in the given options if we write the relation in the form of (x,y) then 4, 5, 2 are the values in the range
