Find asymptotes and intercepts of a rational function

The video tutorial covers solving a mathematical problem involving a function F(x). It begins with identifying vertical asymptotes by factoring the denominator and using the zero product property. Next, it explains how to determine horizontal asymptotes by comparing the degrees of the numerator and denominator. The tutorial then moves on to finding X-intercepts by setting F(x) to zero and solving the resulting equation. Finally, it demonstrates how to calculate Y-intercepts by substituting zero for X in the function.
