Question

whats the domain of
1x^3-1x^2-36x+36/1x^3-17x^2+90x-144

Answer 1

so would that be -inf to inf

Answer 2

The domain is the set of all values of x that will produce a real output. (I assume this is two polynomials over each-other)

If you have a variable in the denominator, we know that the expression in the denominator cannot be 0. So, restriction on the domain would be the values of x for when the denominator is 0.

Answer 3

Thanks Access, I missed the fraction bar. Don't know what I was thinking. :)

Answer 4

\[ \frac{x^{3} - x^{2} - 36x + 36}{x^{3} - 17x^{2} + 90x - 144} \]
This is the expression, correct?

Answer 5

yes

Answer 6

the denominator must not be equal to zero so when you factorize polynomial below you get:
