NettetEvery polynomial function is a rational function. Remember that a rational function R (x) has the form R (x) = P (x) / Q (x) where P (x) and Q (x) are both polynomial functions. If we take Q (x) = 1 (which is a polynomial), we get the rational function R (x) = P (x) / 1 R (x) = P (x) So, every polynomial function is a rational function.

"Nettet14. aug. 2016 · A reason as to why the limits can't exist is because consider 1 = x*1/x (x > 0) as x approaches 0 from the right. If the limit existed we could write lim x * 1/x = lim x * lim 1/x = 0 * (infinity) = 0. But the limit is clearly 1. So saying the limit doesn't exist is … " - Limit of a rational function

Everywhere else however, including $ (1,0)$ the limit exists and is hence continuous.

Then, lim x → ap(x) = p(a) lim x → ap(x) q(x) = p(a) q(a) when q(a) ≠ 0. To see that this theorem holds, consider the polynomial p(x) = cnxn + cn − 1xn − 1 + ⋯ + c1x + c0.
