(x, f(b))

(x, b - 2)

 (b - 2, f(b -2))

 (x, f(b))

 (x, b - 2)

 (b - 2, f(b))

Well, it SAYS x = b-2, so the second and third must be discarded.

Now what?

anonymous · Answer

All we have left is...  (b - 2, f(b -2)) and (b - 2, f(b))

That function notation means you substitute the particular value given.  Which function argument actually contains the ENTIRE x-value?

I deleted your entirely false statement about how bad you are.  Don't say it or think it again!

CAuse D doesn't have the -2 at the end of the b?
