Finding The Domain And Zeros Of Rational Functions Youtube Welcome to our enlightening video that unravels the mysteries of finding the domain and zeros of rational functions, a critical skill in algebraic an. To find the zeroes of a rational function, set the numerator equal to zero and solve for the x x values. when a hole and a zero occur at the same point, the hole wins and there is no zero at that point. example 2. create a function with zeroes at x = 1, 2, 3 x = 1, 2, 3 and holes at x = 0, 4 x = 0, 4. 3. a rational function is zero when the numerator is zero, except when any such zero makes the denominator zero. f(x) = p(x) q(x) = 0 p(x) = 0 and q(x) ≠ 0 f (x) = p (x) q (x) = 0 p (x) = 0 and q (x) ≠ 0. in this case, we need to solve. 2x2 − 8 = 2(x2 − 4) = 2(x − 2)(x 2) = 0 x = 2 or x = −2 2 x 2 − 8 = 2 (x 2 − 4) = 2 (x −. Case 3: if the degree of the denominator = degree of the numerator, there is a horizontal asymptote at y = an bn, where an and bn are respectively the leading coefficients of the numerator and denominator of the rational function. example: f(x) = 3x2 2 x2 4x − 5. in this case, the end behavior is f(x) ≈ 3x2 x2 = 3.
