Question
Determine where each rational function is undefined. Determine whether an asymptote or a hole appears at such numbers.$R(x)=\frac{x^3-2 x^2+4 x-8}{x^2+x-6}$
Step 1
A rational function is undefined where its denominator is zero. Therefore, we need to solve the equation \( x^2 + x - 6 = 0 \). Show more…
