Question
Graph each function and identify the horizontal and vertical asymptotes
Hint:
A rational function is a function that is the ratio of polynomials. Any function of one variable, x, is called a rational function if, it can be represented as f(x) = p(x)/q(x), where p(x) and q(x) are polynomials such that q(x) ≠ 0.
Rational functions are of the form y=f(x)y=fx , where f(x)fx is a rational expression .
- If both the polynomials have the same degree, divide the coefficients of the leading terms. This is your asymptote.
- If the degree of the numerator is less than the denominator, then the asymptote is located at y = 0 (which is the x-axis).
- If the degree of the numerator is greater than the denominator, then there is no horizontal asymptote.
The correct answer is: From the graph we can analyze that the vertical asymptote of the rational function is x = -1 and degree of the numerator is greater than the denominator, then there is no horizontal asymptote.
- Find the asymptotes of the rational function, if any.
- Draw the asymptotes as dotted lines.
- Find the x -intercept (s) and y -intercept of the rational function, if any.
- Find the values of y for several different values of x .
- Plot the points and draw a smooth curve to connect the points. Make sure that the graph does not cross the vertical asymptotes.
The vertical asymptote of a rational function is x -value where the denominator of the function is zero. Equate the denominator to zero and find the value of x .
x2 + 2x + 1= 0
x2 + x + x + 1= 0
x(x + 1) + 1 (x + 1) = 0
(x + 1) (x + 1) = 0
x + 1 = 0 or x + 1 = 0
x = -1
The vertical asymptote of the rational function is x=−1.
This function has no x -intercept and y -intercept at (0,7) . We will find more points on the function and graph the function.
From the graph we can analyze that the vertical asymptote of the rational function is x = -1 and degree of the numerator is greater than the denominator, then there is no horizontal asymptote.
