Evaluate: ("lim")(xvec-2^+) (x^2-1)/(2x+...

Evaluate: `("lim")_(xvec-2^+)` `(x^2-1)/(2x+4)`

Text Solution

Verified by Experts

The correct Answer is:
`oo.`
`L= underset(xto-2^(+))lim(x^(2)-1)/(2x+4)`
`=underset(hto0)lim((-2+h)^(2)-1)/(2(-2+h)+4)`
`=underset(hto0)lim(3-4h+h^(2))/(2h)`
For `hto0,` Numerator`to3` and Denominator `to0`
`:." "Ltooo`
