Simplify the function first to cancel all common factors (if any).So to find the vertical asymptotes of a rational function: A rational function may have one or more vertical asymptotes. But note that there cannot be a vertical asymptote at x = some number if there is a hole at the same number. Here, 'some number' is closely connected to the excluded values from the domain. Vertical Asymptote of a Rational FunctionĪ vertical asymptote (VA) of a function is an imaginary vertical line to which its graph appears to be very close but never touch. Since (x + 2) was striked off, there is a hole at x = -2. Let us factorize the numerator and denominator and see whether there are any common factors.į(x) = / Holes exist only when numerator and denominator have linear common factors.Įxample: Find the holes of the function f(x) = (x 2 + 5x + 6) / (x 2 + x - 2).

Every rational function does NOT need to have holes. We can find the corresponding y-coordinates of the points by substituting the x-values in the simplified function. They can be obtained by setting the linear factors that are common factors of both numerator and denominator of the function equal to zero and solving for x. The holes of a rational function are points that seem that they are present on the graph of the rational function but they are actually not present. Apart from these, it can have holes as well. Now, we will solve this for x.Ī rational function can have three types of asymptotes: horizontal, vertical, and slant asymptotes. Set of all real numbers other than the values of y mentioned in the last step is the range.Įxample: Find the range of f(x) = (2x + 1) / (3x - 2).Set the denominator of the resultant equation ≠ 0 and solve it for y.If we have f(x) in the equation, replace it with y.

To find the range of a rational function y= f(x): The range of a rational function is the set of all outputs (y-values) that it produces. Thus, the domain = Range of Rational Function We set the denominator not equal to zero. Set of all real numbers other than the values of x mentioned in the last step is the domain.Įxample: Find the domain of f(x) = (2x + 1) / (3x - 2).Set the denominator ≠ 0 and solve it for x.To find the domain of a rational function y = f(x):

The domain of a rational function is the set of all x-values that the function can take. This is the key point that is used in finding the domain and range of a rational function. See also interquartile range and quartiles.Any fraction is not defined when its denominator is equal to 0. Values higher than Q3+1.5xIQR or lower than Q1-1.5xIQR are considered outliers and are plotted above the top whisker or below the bottom whisker. The ends of the whiskers are marked by two shorter horizontal lines. The vertical lines protruding from the box extend to the minimum and the maximum values of the data set, as long as these values are not outliers. The horizontal line inside the box is the median. Therefore the vertical width of the central box represents the inter-quartile deviation. The bottom side of the box represents the first quartile, and the top side, the third quartile. The box plot is also referred to as box and whisker plot or box and whisker diagram Elements of the box plot What is a box plotĪ box plot is a diagram that gives a visual representation to the distribution of the data, highlighting where most values lie and those values that greatly differ from the norm, called outliers. These measures are displayed to the left of the chart.For more details on the dispersion of the data set, you may click on the More dispersion data link located on the left of the plot. When you submit your data, the server calculates the measures that will be used to plot the diagram. To clear the graph and enter a new data set, press 'Reset'.

You may also copy and paste data from another window such as an open document, spreadsheet pdf file or another web page. You do not need to specify whether the data is from a population or a sample. Individual values may be entered on separate lines or separated by commas, tabs or spaces. You must enter at least 4 values to build the box plot. This page allows you to create a box plot from a set of statistical data:
