Question

Which of the following rational expressions has the domain restrictions X = -6 and x = 1?

Answer 1

The domain of the function is possible values of independant varaible such that function is defined or have real values.

So the expression

`((x+2)(x-3))/((x-1)(x+6))`

is not defined for x = -6 and for x = 1, as expression becomes undefined for this values of x (Denominator becomes 0).

So answer is,

`((x+2)(x-3))/((x-1)(x+6))`

Option B is correct.
