Question

find domain for the following​

Answer 1

Heya!!

F(x) = √{(x² - 1)/(|x| - 3) }

For Domain of F(x) ( x² - 1 ) ≥ 0 And

( |x| - 3 ) > 0

( x² - 1 ) ≥ 0 And ( |x| - 3 ) > 0

x² ≥ 1 And |x| > 3

|x| ≥ 1 And |x| > 3

x ≥ 1 OR x ≤ -1 And x > 3 OR x < -3

x € ( -∞ -3 ) u ( 3 ∞ )

Note:-

Here "€" Repsent belongs to.

And "u" Repsent union.
