This defines a domain of f,

`x in (2-alpha,2+alpha)`

`(i)` Function defined in an open interval.

(ii) We can discuss continuity and differentiability in an open interval.

Please specify more about function thenmore detail answer possible.

consider two condition `x^2-3x-10`  and |x-2|<α on a real number x, where a is a positive real number
i. the range of values of α such that |x-2|<α is a necessary condition for `x^2-3x-10`  is (A)
2. the range of values α such that |x-2|<α is a sufficient condition for `x^2-3x-10`   is (B)
