## anonymous 4 years ago Guys can you pls help me answering this prob. Evaluate lim x-2 over x^2-1 as x approaches 2?

1. anonymous

replace x by 2, get zero

2. anonymous

$\lim_{x\rightarrow 2}\frac{x-2}{x^2-1}=\frac{2-2}{2^2-1}=\frac{0}{3}=0$

@ Sattelite thanks for me helping me. :)

yw most every function given by and equation is continuous on its domain, meaning to find a limit you can simply evaluate the funtion. you will only have more work to do the funciton is undefined at the limit point, specifically if you get $\frac{0}{0}$ when you evaluate the function
