12

−12

−8

8

Answer 1

I'm not sure I understand

Answer 2

neither do i.

Answer 3

I can't really tell what you are trying to ask, maybe you could write it out again?

Answer 4

\[g(x)=\frac{ 1 }{ 2x-2 }\]Is that what you mean?

Answer 5

Well if that is the case then\[g(-4)=\frac{ 1 }{ 2(-4)-2 }=\frac{ -1 }{ 10 }\]

Answer 6

Now all that is left is to put that number in to the f(x) and then job done!

Answer 7

this is exactly how it looks in the lesson.

Answer 8

Are there any brackets around anything in the g(x)?

Answer 9

nope.
there is just the parentheses around the x
