WebExample 4 Solving Rational Inequalities Rational inequalities can also be solved using a sign analysis procedure. With rational inequalities, however, there is an additional area of consideration – values of x that make the rational expression undefined. WebYou find whether your function will ever intersect or cross the horizontal asymptote by setting the function equal to the y or f(x) value of the horizontal asymptote. If you get a …
WebIf the graph is decreasing or f' (𝑥) is negative, write a negative sign on the diagram in this region. Mark the 𝑥 coordinates of all stationary points on the sign diagram line. In the function below, there are stationary points marked at 𝑥 = -4, 𝑥 = -1.5 and 𝑥 = 5. These are then written on the axis of the sign diagram.
