Solved Graphing Rational Functions Worksheet Sketch The G

First ill find the vertical asymptotes if any for this rational function.

Sketch a graph of each rational function. Find the horizontal asymptote. Voiceoverright over here i have the graph of f of x and what i want to think about in this video is whether we could have sketched this graph just by looking at the definition of our function which is defined as a rational expression. Show all asymptotes andor holes.

There is a couple of. How to graph a rational function. The properties such as domain vertical and horizontal asymptotes of a rational function are also investigated.

A step by step tutorial. Find the vertical asymptotes. To graph a rational function we first find the vertical and horizontal asymptotes and the x and y intercepts.

Find the local extrema. To graph a rational function you find the asymptotes and the intercepts plot a few points and then sketch in the graph. It shows you how to identify the vertical asymptotes by setting the denominator.

We have 2x plus 10 over 5x minus 15. So the first thing we might want to do is identify our horizontal asymptotes if there are any. Y 4 x2 1 2.

A step by step tutorial. So lets say i have y is equal to 2x over x plus 1. And i said before all you have to do is look at the highest degree term in the numerator.

Lets do a couple more examples graphing rational functions. Find the y values of each local extremum. Once you get the swing of things rational functions are actually fairly simple to graph.

A function basically relates an input to an output theres an input a relationship and an output. Learn how to graph a rational function. So 0 4 is the y intercept.

The line yb is a horizontal asymptote if the graph approaches yb as x increases or decreases without bound. Sketch a graph of each rational function. The line xa is a vertical asymptote if the graph increases or decreases without bound on one or both sides of the line as x moves in closer and closer to xa.

Lets work through a few examples. Y 3x x2 3x now having already said that the denominator cannot be zero we can say that there will be no x intercepts because the denominator is the only part with x terms. This algebra 2 precalculus video tutorial explains how to graph rational functions with asymptotes and holes.
