Thus −2. A rational function is a fraction of polynomials. Determine if the numbers are zeros of the function: 4. So, to find the zeros of a rational function we simply find the zeros of the NUMERATOR. Here is a set of practice problems to accompany the Finding Zeroes of Polynomials section of the Polynomial Functions chapter of the notes for Paul Dawkins Algebra course at Lamar University. 3, 2, ½; f(x) = 3x3 + 11x2 – 2x + 8 5. linalg imports most of them, identically named functions from scipy. Questions contain using the Rational Zeros Theorem, finding rational zeros, upper and lower bounds, and using Descartes Rule of Signs. This is a more general case of the Integer (Integral) Root Theorem (when leading coefficient is `1` or `-1`). Recall that the Division Algorithm states that given a polynomial dividend f(x) and a non-zero polynomial divisor d(x) where the degree of d(x) is less than or equal to the degree of f(x), there exist uni… Characteristic 2 1 7 x x y − − = 2 2 5 7 10 + + + = x x x x y 2 2 7 12 9 − + − = x x x y ©2 o2i0 91e2 b jK hu1t PaA GS9oCftmwPaJrpe 7 nLhLfC 6.o z FAGlol e Kroi 3g fhkt rs v BrXehs Tekr RvKe3d W.6 v fMVaXdRe h awigtvhd iI 8n9f Bibn ciRt0e o dAOlrgae qb9r IaL T2F.Z Worksheet by Kuta Software LLC 11) 5, −1, 0 12) −3, − 1 3, 5 13) 5 3, 1, −1 14) 2, 5 3, −5 Find all zeros by factoring each function… Here is a set of practice problems to accompany the Zeroes/Roots of Polynomials section of the Polynomial Functions chapter of the notes for Paul Dawkins Algebra course at Lamar University.
