For x in R , lim(xrarr oo) ((x-3)/(x+2))...

For `x in R , lim_(xrarr oo) ((x-3)/(x+2))^x = `

A

e

B

`e^-1`

C

`e^-5`

D

`e^5`

Text Solution

Verified by Experts

The correct Answer is:
C
We have,
` lim_(xto oo) ((x-3)/(x+2))^x = (1+(-5)/(x+2))^x`
` lim_(xto oo) ((x-3)/(x+2))^x = e ^(lim_(xto oo)-(5x)/(x+2))=e^-5[lim_(xto oo)(-5)/(1+(2)/(x)=-5)]`
