Graphing Functions Calculator plots the graph for any given functions. It helps us to visualize the nature of graph of the given function instantly.

A function is given below as a default input for this calculator. Plug in some values of x and substitute it in the function to get the coordinates. A graph is plotted according to the values of x and y, when you click on "Graph".
 

Steps for Graphing Functions Calculator

Step 1 :  

We know that graph is made up of (x,y) co-ordinates. Hence choose some values of x and substitute it in function of y to get y co-ordinates.



Step 2 :  

Plot the graph by marking the values of x as well as corresponding values of y. we get the desired graph.

  1. Plot a graph for the given function y = x3


    Step 1 :  

    At x = - 0.5
    => y = (- 0.5)3
         = - 0.125


    At x = -1
    => y = (-1)3 = -1


    At x = 0
    => y = 03 = 0

    At x = 1
    => y = 13 = 1


    The coordinates of the given points are (- 0.5, - 0.125), (-1,-1), (0,0) and (1,1).



    Step 2 :

    Answer  :  

    The above graph represents the given function y = x3



  2. Plot the graph for the given function y = 4x3 - 3.


    Step 1 :  

    At x = - 0.25
    => y = 4(-0.25)3 - 3
         = -3.015625.


    At x = -1
    => y = 4(-1)3 - 3
         = -4-3
         = -7


    At x= -1.5


    => y = 4(-1.5)3 - 3


            = -13.5 - 3


            = -16.5


    At x = 1
    => y = 4(1)3 -3
         = 4 - 3
         = 1


    At x = 0
    => y = 4(0)3 - 3
         = -3


    At x = 0.75


    => y = 4(0.75)3 - 3


            = 1.6875 - 3
            = -1.3125.


    The coordinates are (-0.25,-3.0156),(-1,-7), (-1.5,-16.5), (0,-3), (0.75, -1.3125) and (1,1)



    Step 2 :
