(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Find the constants a and b such that the function is continuous on the entire line.

2. Relevant equations

g(x)={4 sinx/x, x<0

{a-2x, x> or = 0

3. The attempt at a solution

Possible discontinuity at x=0

f(0^+)=a-2x=a-2(0)=a

f(0^-)=4sinx/x=4sin(0)/(0)

i am stuck, wouldn't f(0^-) not exist then? i really don't know what I am doing on this entire assignment as i have been gone from school for a week so if anyone knows how to do this, I would love for you to help me on AIM or MSN tonight.
