Using the domain, it is found that x = -8 is excluded for the product.
The domain of a function is the <u>set that contains all possible input values</u>.
- In a fraction, the <u>denominator cannot be 0</u>.
In this problem, there are two fractions, and the points outside the domain, that is, the roots of the denominators, are excluded.
For the first fraction, they are:
Hence, x = -2(not an option) is excluded.
- x = 0 can be factored with the numerator of the second fraction, so not excluded.
For the second fraction, the roots of the denominator are:
Which is a quadratic equation with <u>coefficients</u> , hence:
x = -3 can be factored with the numerator of the first fraction, so only x = -8 is excluded.
