Given:

To find:
The values of f(2) and f(5).
Solution:
If an ordered pair
is in the function
, then
.
In the given set of ordered pairs one ordered pair is (2,3). So, by using the above definition, we get

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

Therefore, the value of f(2) is 3 and the value of f(5) is 6.
Answer:
yes
Step-by-step explanation:
Answer:
x=-2, y=-4. (-2, -4).
Step-by-step explanation:
2x-y=0
y=x-2
------------
2x-(x-2)=0
2x-x+2=0
x+2=0
x=0-2
x=-2
y=-2-2=-4
