Geometry Tutoring Online

Geometry

Geometry, a branch of mathematics concerned with shapes and their properties is a pre-requisite for advanced mathematical courses.

Are you having a hard time tackling it?

After completing your first algebra course, geometry is next in line. Your brain must now shift from understanding abstract numbers to calculating the dimensions of abstract spaces.

Along with our tutors, one step at a time, we ensure you master the basic geometrical concepts. After mastering basic geometry skills, you will no longer feel intimidated by complex geometrical problems you may face in school.

Working with our experts helps in improving your geometrical skills which in turn increases your confidence level.

We deal with topics such as geometrical proofs, solving for the areas of shapes, graphical representation, the Pythagorean Theorem, simple measurements and distance word problems.

Asymptotes

Asymptotes

Share
An asymptote for a function f(x) is a straight line which is approached but never reached by f(x).
 

Vertical Asymptotes

These are the vertical lines near which the function f(x) becomes infinite. If the denominator of a rational function has factors of the type (x - a) in the numerator, then the rational function will have a vertical asymptote at x = a for each (x-a).

Horizontal Asymptotes

A horizontal asymptote is a line y = a, such that the values of f(x) get increasingly close to the number a as x gets large in either the positive or negative direction. Rational functions have horizontal asymptotes when the degree of the numerator is the same as the degree of the denominator.
 

Oblique Asymptotes

An oblique asymptote is an asymptote of the form y = ax + b with ‘a’ being non-zero. Rational functions have oblique asymptotes if the degree of the numerator is one more than the degree of the denominator.

Use quotients of polynomials to describe the graphs of rational functions.
 

To draw the graph of a rational function, we must find the asymptotes, the intercepts and a few points and then plot them on the graph. Once you get known to the things, rational functions are actually very easy to graph.
 

Try these problems

 
  1. Find the horizontal and vertical asymptotes of the rational function in question 15 above.

    1. y=1 and x= -5, respectively

    2. x=1 and y= -5, respectively

    3. y=3 and x = -5, respectively

    4. y=-1 and x= 5, respectively

    Answer: 1

    Explanation:

    The simplified rational function is  
         
    1. The vertical asymptote occurs where the denominator is zero, i.e. at x = -5.

    2. For the  horizontal asymptote , x= :


    Y= = 1




  2. Find the horizontal and vertical asymptotes of the rational function given below:





    1. Vertical  asymptotes: x= -5 , x=2 ; Horizontal asymptote: y = 1
    2. Vertical  asymptotes: x= -5 ; Horizontal asymptote: y = 1
    3. Vertical  asymptote: x= -5 ; Horizontal asymptote: y = -2
    4. Vertical  asymptotes: x= -5, x=2 ; Horizontal asymptote: y = 4


      Answer: 2
