How to Evaluate a Polynomial in Function Notation

WebEVALUATING A POLYNOMIAL Consider having a polynomial p(x)=a0 + a1x+ a2x2 + ···+ anxn which you need to evaluate for many values of x.How do you evaluate it? This may seem a strange question, but the answer is not as obvious as you might think. The standard way, written in a loose algorithmic for-mat: poly= a0 forj=1:n poly= poly+ ajxj end Webin polynomial evaluation, it is generally a small gain and accompanied by an increase in the number of additions and the complexity of the algorithm . If preprocessing of the polynomial coeﬃcients is not used, Horner gives a minimum arithmetic evaluation [3, 5]. If we diﬀerentiate (5), we get: fN [a,z]=qN−1[b,z]+qN−1 [b,z](z −z0), (10)
