Solution
- The question tells us to determine the codomain of the following rational function:

- The codomain of the function is the possible values that f(x) can take.
; From the function, we can see that:
![\begin{gathered} f(x)=(x+3)/(x-1) \\ \text{when }x=1 \\ f(1)=(1+3)/(1-1)=(4)/(0) \\ \\ \text{Thus, f(1) leads to an undefined value. As such,} \\ x\\e1 \end{gathered}]()
- Thus, we can conclude that the codomain is:
![undefined]()
