Using function concepts, it is found that:
- The domain of the function is all real numbers.
- The range of the function is all real numbers greater than or equal to -2.
The domain of a function is the set that contains all possible input values. In a graph, it is the values assumed by the x-axis.
- In this graph, x assumes all values from negative infinity to positive infinity, thus the domain is all real numbers.
The range of a function is the set that contains all possible input values. In a graph, it is the values assumed by the y-axis.
- In this graph, y assumes values from -2 to positive infinity, thus the range is all real numbers greater than or equal to -2.
