Question

The domain of the piece wise function is A graph the function B use the graph to determine the function range

Answer 1

Given:

There are given the function:

`f(x)=\begin{cases}x+5\text{ f(x)<4} \\ x-5\text{ f(x)}\ge4\end{cases}`

Step-by-step explanation:

(a):

To graph the given function, we need to see that the first graph is less than 4 and the second graph will be greater than and equal to 4.

So,

The graph of the given function is shown below:

Final answer:

Hence, the correct option is A.
