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.

Problems on Graphing Functions Calculator

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 : 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 :
