We have the following:
we can know the result, evaluating the point (0,0)
[tex]\begin{gathered} y=f\mleft(0-4\mright)-4=-8 \\ y=f\mleft(0-4\mright)+4=0 \\ y=f\mleft(0+4\mright)+4=8 \\ y=f\mleft(0+4\mright)-4=0 \end{gathered}[/tex]
the answer lies between points b and c.
Now,
to know the answer we must see the dotted and dim line, which starts from x = -4, therefore the correct answer is option b.
