Let's practice graphing a couple of rational functions in constant over linear form. Graphing a Rational Function in Constant Over Linear Form: Example 1 Graph the rational function {eq}f(x)=\frac{1}{x-5} {/eq}. Step 1:Find a vertical asymptote. ...
To graph a rational function:Factor the numerator and denominator, if possible; check if anything can be cancelled out. Solve the numerator's factors for their zeroes; these will be the x-intercepts of the graph. Solve the denominator's factors for their zeroes, keeping in mind that the ...
A rational function is a function which is a fraction where both numerator and denominator are polynomials. That is, a ratio of two polynomials P(x) and Q(x), where the denominator Q(x) is not equal to zero. Before we learn, how to graph rational functions, first we have to be awar...
Steps to Graph a Rational Function • 1. Factor and simplify if you can • 2. Look for the vertical asymptote and horizontal asymptote • 3. Draw asymptotes as dotted lines on your graph • 5. Find 3 x values greater than the vertical asymptote and 3 less than the vertical asympto...

A rational function is a mathematical function that can be expressed as the ratio of two polynomials. It is typically written in the form f(x) = p(x)/q(x), where p(x) and q(x) are polynomials and q(x) is not equal to 0. Why is graphing often used to find the...

Rational functiony=f(x)=P(x)/Q(x) is a ratio of twopolynomialsP(x) and Q(x). As for example, y=f(x)=(x2+1)/x=x+1/x is a rational function. There are twoasymptotesy=x and x=0.The graph of this rational function is two curves which are situated between this two asymptot...
In this paper, we will examine the mathematical knowledge that prospective mathematics teachers draw upon when graphing function graphs and curves, with a special focus on the occurrence of asymptotes. Three tasks which involved a graph of a rational and exponential function ...
