f(x) =
The denominator of f(x) cannot be zero as this would make f(x) undefined. Equating the denominator to zero and solving gives the value that x cannot be.
solve : 3x + 15 = 0 ⇒ 3x = - 15 ⇒ x = - 5 ← excluded value
Domain x ∈ R , x ≠ - 5

Step-by-step explanation:
Given
See attachment for relation
Required
What type of function is it?
The relation can be represented as:
Where
and
Notice that the range has an occurrence of 10 (twice)
i.e.
and
In function and relations, when two different values in the domain point to the same value in the range implies that, <em>the relation is many to one.</em>
