Answer:
For [tex]d=-2[/tex] rational expression will be undefined.
Step-by-step explanation:
Given function is [tex]\frac{6d-4}{d+2}[/tex]
We need to find for what value of variable [tex]d[/tex] this rational expression will be undefined.
The rational expression will be undefined if the denominator of the expression will become zero.
So, let us plug denominator equal to zero.
[tex]d+2=0\\\\Subtracting\ both\ side\ 2\\\\d+2-2=-2\\\\d=-2[/tex]
Hence, this rational expression will be undefined if the value of variable [tex]d=-2[/tex].
