उत्तर

`lim_(x -> 2) (x - 2)/(x^2 - x - 2) =  lim_(x -> 2) ( x - 2)/((x - 2)(x + 1))`

= `lim_(x -> 2) (x - 2)/(x + 1)`

x  1.9 1.99 1.999 2.001 20.1 2.1
f(x)

`1/(1.9 + 1)`

= `1/2.9`

= 0.34

`1/(1.99 + 1)`

= `1/2.99`

= 0.33

`1/(1.999 + 1)`

= `1/2.99`

= 0.33

`1/(2.001 + 1)`

= `1/3.001`

= 0.33

`1/(2.01 + 1)`

= `1/3.01`

= 0.33

`1/(2.1 + 1)`

= `1/3.1`

= 0.32

`lim_(x -> 2) (x - 2)/(x^2 - x - 2)` = 0.3
