What does the numerator of a rational function reveal?
Previously we saw that the numerator of a rational function reveals the x x -intercepts of the graph, whereas the denominator reveals the vertical asymptotes of the graph. As with polynomials, factors of the numerator may have integer powers greater than one.
Which is the problem of writing a rational function?
Problem 1: Write a rational function f that has a vertical asymptote at x = 2, a horizontal asymptote y = 3 and a zero at x = - 5. Since f has a vertical is at x = 2, then the denominator of the rational function contains the term (x - 2).
How do you graph a rational function in math?
To graph a rational function, begin by marking every number on the x-axis that is a root of the denominator. (The denominator might not have any roots.) Draw a vertical dashed line through these points. These vertical lines are called vertical asymptotes.
Can a rational function be written in factored form?
A rational function written in factored form will have an x x -intercept where each factor of the numerator is equal to zero. (An exception occurs in the case of a removable discontinuity.) As a result, we can form a numerator of a function whose graph will pass through a set of x x -intercepts by introducing a corresponding set of factors.
