How to fill out 2-7 graphing rational functions

How to fill out 2-7 graphing rational functions?

1. Start by identifying the rational function. A rational function is a function that is expressed as the ratio of two polynomials. It can be written in the form f(x) = P(x) / Q(x), where P(x) and Q(x) are polynomials.
2. Determine the domain of the rational function. The domain is the set of all possible input values for the function. To find the domain, set the denominator Q(x) equal to zero and solve for x. The values of x that make the denominator zero must be excluded from the domain.
3. Calculate the vertical asymptotes, if any. Vertical asymptotes occur when the value of x approaches a certain number, and the function approaches infinity or negative infinity. To find the vertical asymptotes, set the denominator Q(x) equal to zero and solve for x. The vertical asymptotes will be the values of x that make the denominator zero, except for those that are excluded from the domain.
4. Find the horizontal asymptote, if any. A horizontal asymptote is a horizontal line that the function approaches as x approaches positive or negative infinity. To determine the horizontal asymptote, compare the degrees of the numerator and denominator polynomials. If the degree of the numerator is less than the degree of the denominator, the horizontal asymptote is y = 0. If the degrees are equal, the horizontal asymptote is the ratio of the leading coefficients of the numerator and denominator. If the degree of the numerator is greater than the degree of the denominator, there is no horizontal asymptote.
5. Determine the x-intercepts, if any. The x-intercepts occur when the numerator P(x) is equal to zero. Solve the equation P(x) = 0 to find the x-values at which the function crosses the x-axis.
6. Find the y-intercept. The y-intercept is the point where the function intersects the y-axis. To find it, evaluate the function at x = 0 and determine the corresponding y-value.
7. Plot additional points to accurately represent the graph of the rational function. Choose various values of x, evaluate the function at those points, and plot the corresponding (x, y) coordinates on a graph.
