Question:
Consider the relation {(−5, 8), (4, −2), (4, 1), (3, 0)} . What integer is in the domain?
A 8
B -2
C -5
D -1
Answer:
Option C
The domain is -5, 4, 4, 3
Solution:
Given relation is:
[tex]{(-5, 8), (4, -2), (4, 1), (3, 0)}[/tex]
Let us understand about domain and range
Domain refers to the set of possible input values
Range is the set of possible output values
Thus the input values in given relation are:
(x, y) = (-5, 8) , (4, -2) , (4, 1) , (3, 0)
The input values are values of "x"
Input values = -5, 4, 4, 3
Thus the domain of given relation are -5, 4, 4, 3
Thus option C is correct
