You want to make sure that you satisfy these conditions:

$\displaystyle \lim_{x\to-9^-}f\left(x\right)=\lim_{x\to-9^+}f\left(x\right)$

and

$\displaystyle \lim_{x\to7^-}f\left(x\right)=\lim_{x\to7^+}f\left(x\right)$

What will then happen is this: You will have generated a system of equations, and now you can easily solve for a and b.

Can you try to take it from here? - Jan 3rd 2009, 05:17 PMskeeter

i generated the equations : 8=-9x + b and -8=7x + b and found b to be -1.

However, I do not know how to find a.. =[

EDIT: I think I got it.. I got a and b to both equal -1.

Is that correct? - Jan 3rd 2009, 05:31 PMskeeter
