Answer:
The correct option is 1.
Step-by-step explanation:
If a rational function is defined as
then the excluded values of a rational expression are zeroes of the denominator. In other words, the excluded values of a rational expression are those values of x for which Q(x)=0.
It is given that the excluded values of a rational expression are –3, 0, and 8. It means denominator have three zeroes or degree 3.
Only expression 1 has denominator with degree 3. The first expression is
Equate denominator equal to 0.
The roots of this equation are excluded values of the rational expression.
Taking out the common factor.
Using zero product property, we get
The excluded values of first rational expression are –3, 0, and 8. Theretofore the correct option is 1.
