A function maps input to single output.
- The domain of given mapping is {-1}
- A range of given mapping can be {4,9,15,0}
- The given mapping is not a function.
The given mapping is:
{(-1, 4), (-1,9), (-1; 15), (-1,0)}
What is domain?
The set of input values to a mapping is called that mapping's domain.
What is range?
The set of values in which the output is located.
For given relation, only one input '-1' is used. Thus, the domain of given mapping is {-1} (these curly brackets show a set and that set contains single value)
For given relation, the output values are {4,9,15,0}. This can be taken as range of this mapping.
When is a mapping(or relation) a function?
When the paired association(when input is connected to output) is such that one input connects only to single output, then such relation or such mapping is called a function.
Since, for given pairs of values, we have -1 as input and there are multiple outputs to that input, thus it is not a function.
Thus,
The domain of given mapping is {-1}
A range of given mapping can be {4,9,15,0}
The given mapping is not a function.
