Q.
Determine whether relation is function.
Q. Consider the following domain and range for the relation from set X to set Y such that x−y=2n;where n is a integer.
X:{4, 5, 6, 7}Y:{2, 6, 7, 9}x∈X & y∈Y
Is this a function?
X:{4, 5, 6, 7}Y:{2, 6, 7, 9}x∈X & y∈Y
Is this a function?
- Yes. It is a function as the number of elements of domain equals the number of elements in y.
- No. It is not a function.
