Graph rational functions with holes
WebFeb 13, 2024 · This is the essence of dealing with holes in rational functions. You should cancel what you can and graph the function like normal making sure to note what \(x\) values make the function undefined. Once the function is graphed without holes go back and insert the hollow circles indicating what \(x\) values are removed from the domain.

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.

Find the x - and y … WebA rational function is a quotient of two functions. The graph of a rational function usually has vertical asymptotes where the denominator equals 0. However, the graph of a rational function will have a hole when a …
WebFind the hole (if any) of the function given below . f(x) = 1/(x + 6) Solution : Step 1: In the given rational function, clearly there is no common factor found at both numerator and denominator. Step 2 : So, there is no hole … WebGraphing Rational Functions. In Example 9, we see that the numerator of a rational function reveals the x-intercepts of the graph, whereas the denominator reveals the vertical …
