Answer:
Option B is correct
Explanation:
Given: A solution x =3 was extraneous for his function.
Extraneous solution defined as a root of a transformed equation that is not a root of the original equation because it was excluded from the domain of the original equation.
The only function from the given options
f(x) =
has the solution x =3
therefore,
3 is excluded from the domain of the
because it would make the denominator of one of the fractions zero and division by zero is not allowed.
Therefore, it cannot be a root of the equation
