The domain of a function is the set of input values the function can take.
The domain of the graph is [tex]\{x |1 \le x < 5\}[/tex]
From the graph of the piece-wise function, we have the following highlights
- The x-values begin at x = 1 with a closed circle
- The x-values end at x = 5 with an open circle
The above highlights can be represented using the following inequality
1 <= x < 5
Rewrite properly as:
[tex]\{x |1 \le x < 5\}[/tex]
Hence, the domain of the graph is [tex]\{x |1 \le x < 5\}[/tex]
