Sign analysis rational functions
WebUnbounded limits don't exist; however, they are different from limits such as a_n = (-1)^n ; this sequence doesn't have a limit merely because it is alternating between 1 & -1, though its absolute value stays at 1. Unbounded limits aren't oscillating - they keep getting bigger or smaller. So we define infinity & - infinity to represent that. WebJul 18, 2024 · This function has no poles except possibly at $\infty$. All other singularities are removable. So if we restrict this function to $\mathbb C$, it's entire. So if it has no pole at $\infty$, then it is constant and thus rational due to Liouville's theorem. If it has a pole at $\infty$, then it is a polynomial

WebTo make a sign chart for a rational function, draw a number line and locate the zeros of the numerator and label them with a 0, since the function value is zero there. Locate the zeros of the denominator, and label them with a u, since the function is undefined at these values. Use what you know about the graphs of polynomial functions to ...
