Given:

$f=\{(1,2),(2,3),(5,6),(7,8)\}$

To find:

The values of f(2) and f(5).

Solution:

If an ordered pair
(x,y) is in the function
, then
f(x)=y .

In the given set of ordered pairs one ordered pair is (2,3). So, by using the above definition, we get

f(2)=3

In the given set of ordered pairs one ordered pair is (5,6). So, by using the above definition, we get

f(5)=6

Therefore, the value of f(2) is 3 and the value of f(5) is 6.
