WebAt first, rational functions seem wildly complicated. It isn't like the equation of a line, (linear function), f (x) = mx +b, where you just have slope and intercept to worry about. With a little practice, though, you can figure out a lot about a graph by looking at the parts of these rational functions. WebAn intercept of a rational function is a point where the graph of the rational function intersects the x x - or y y -axis. For example, the function y = \frac { (x+2) (x-1)} { (x-3)} y = (x−3)(x+2)(x−1) has x x -intercepts at x=-2 x = −2 …
