Question

8/15
consider the function:
{(3, 11), (4, 18), (5, 27), (6, 38)}
what is the range?
{4, 11, 5, 18}
{3, 11, 4, 18}
{3, 4, 5, 6}
{11, 18, 27, 38}

Explanation:

Step1: Identify range definition

The range of a function (given as ordered pairs) is the set of all the second values in each pair.

Step2: Extract second values

From the pairs {(3, 11), (4, 18), (5, 27), (6, 38)}, the second values are 11, 18, 27, 38.

Step3: Form the range set

Group these values into a set.

Answer:

{11, 18, 27, 38}
