Is there a quick way of sketching graphs such as quadratic parabolas and non-complex parabolas?

I don't know about any of a easy way to draw them but I want to tell you that any two parabolas are the same, but maybe shifted and zoomed or shrunken.

Hi Misaki,

 

Do you mean by hand?

 

Anyway, if you are just looking for a beautiful, easy to use graphing calculator then Desmos is for you :)

There is a lot about graphing that you should learn to do by hand but this tool is fantastic for checking your answers :)

How to graph parabolas.

1) Find the roots that is where y=0

2) Find the axis of symmetry

3) Find the vertex

4) Find the y intercept  where x=0   that is really easy to find.

5) Graph it.

 

If you give me an example I will work it for you :)
