Answer
$\text{Domain: }
(1,4)
\\\text{Range: }
(-4,2)
$
Work Step by Step
Using the table of values below, the graph of the given equation, $f(x)=
4-2x
,\text{ }
1\lt x\lt4
,$ is shown above.
Based on the graph its domain and range are as follows:
\begin{array}{l}\require{cancel}
\text{Domain: }
(1,4)
\\\text{Range: }
(-4,2)
.\end{array}
