How can you identify a rational function

Web10 de fev. de 2024 · 3. Find the zeros. A rational function has a zero when it's numerator is zero, so set N ( x) = 0. In the example, 2 x2 - 6 x + 5 = 0. The discriminant of this quadratic is b2 - 4 ac = 6 2 - 4*2*5 = 36 - 40 = -4. Since the discriminant is negative, N ( x ), and consequently f ( x ), has no real roots. The graph never crosses the x -axis. WebThis algebra 2 / precalculus video tutorial explains how to graph rational functions with asymptotes and holes.
