Graphing equations is a easy job but it will be tedious when you are a bit careless for plotting the graph.Here is a easy tool that helps you out.You just have to enter the equation for which graph has to be plotted and get the graph instantly.

Below is given a default equation which is in the form of y = f(x), click "Graph". First, it plugs different values of x and finds the y value. Then, determines the coordinates and plot the graph.

Step 1 :  

Read the given equation and observe whether it is of form y = f(x) if it is not convert it.



Step 2 :  

Plug in the desired values in the equation and get the values of y. Make a table out of it.



Step 3 :  

Plot the points along y versus x to get the graph.

  1. plot the graph: y = 4x2


    Step 1 :  

    The given function is y = 4x2



    Step 2 :  

    For x = -1, y = 4(-1)2 = 4
        x = 1, y = 4(1)2 = 4
        x = 3, y = 4(3)2 = 36
        x = 5, y = 4(5)2 = 100



    Step 3 :  

    The graph is


    Graphing Equation Example



    Answer  :  

    The coordinates are (-1,4), (1,4), (3,36) and (5,100).



  2. y = x


    Step 1 :  

    The given function is y = x



    Step 2 :  

    For x = -1, y = -1
        x = 1, y = 1
        x = 3, y = 3
        x = 5, y = 5



    Step 3 :  

    The graph is


     Graphing Equation Example



    Answer  :  

    The coordinates are (-1, 1), (1,1), (3,3) and (5,5).
