Holes and vertical asymptotes of rational functions. Similarly you can solve the y intercept by setting the value of x to zero and solving the equation.
X x or.
How to find y intercept of a rational function. How to find the x and y intercepts of rational functions. This video explains how to determine the x intercepts y intercepts vertical asymptotes and horizontal asymptote of a rational function site. Notice that 0 is the x coordinate because on the y axis x 0 to find the x intercept we must substitute in 0 for y or f x.
For example the function. You can find the x intercept of the equation by setting the value of y to zero and solving the equation. There is a y intercept at.
And then solve by cross multiplying. Finding the intercepts of a rational function is similar to finding the intercepts of other normal equations. To find the y intercept we must substitute in 0 for each x.
An intercept of a rational function is a point where the graph of the rational function intersects the. Y x 2 x 1 x 3 y frac x 2 x 1 x 3 y x 3 x 2 x 1. 0 x 10 x 10 there is a y intercept at.
This video is provided by the learning assistance center of howard community college. Notice that 0 is the y coordinate because on the x axis y 0.
