Question

domain of the function f(x) =x²+2x-8/x-2is​

Answer 1

Step-by-step explanation:

$f(x) = {x}^{2} + 2x - \frac{8}{x} - 2 \\ = \frac{ {x}^{3} + 2 {x}^{2} - 8 - 2x}{x}$

by the above equation we clearly see that f(x) is defined for all real numbers except 0.

so, the domain of f(x) is R - {0}.
