Question

Domain of the function f(x)=x^2+2x-6/x-2 is:

A. R
B. R-{2}
C. (-∞, -4) U (2, ∞)
D. Empty set ∅

Answer with method and don't fücking answer if you don't know.

​

Answer 1

Answer:

$\sf \: f(x) = \frac{ {x}^{2} + 2x - 6 }{x - 2} \\ \\ \sf \: \: the \: function \: f(x) \: will \: \: exist \: iff \: \\ \: \: \: \: \sf \: x - 2 \neq \: 0 \\ \: \sf \implies \: x \neq \: 2$

$so, \\ \:domain \: \: \: D_f\:=\:R\:-\: \{2 \}$
