Graphing is usually used to represent the given set of data in graphical format. Graphing is used to study the characteristics of the given data. Graphing is mainly used in algebra problems. In algebra, the topics, slope intercept form, linear equation and non linear equation are usually represented in graph format.

When the function is entered, it automatically generates the graph for the given function. Free Graphing Calculators are easy to solve and those free calculators gives step by step explanation.

Graphing Calculator is a tool which makes calculations easy and fun. It is used to plot an equations and inequality. Try our Graphing Calculator and get your problems solved instantly.

Below is a given default equation with minimum and maximum values of x and y coordinates, click "Submit". It will plug in different values of x to find y coordinates and plot the graph.

## Steps for Graphing Calculator

Step 1 :

Choose different values for "x" zero and solve for y to get different coordinates.

Step 2 :

Mark all the coordinates in the graph and join it.

## Examples on Graphing Calculator

1. ### Graph y = 3x + 5

Step 1 :

Given equation: y = 3x + 5

At x = 0
=> y = 3x + 5
=> y = 3(0) + 5
=> y = 5
At x = 1
=> y = 3x + 5
=> y = 3(1) + 5
=> y = 3 + 5
=> y = 8
At x = -2
=> y = 3(-2) + 5
=> y = -6 + 5
=> y = -1
At x = -3
=> y = 3(-3) + 5
=> y = -9 + 5
=> y = -4

So, the coordinates are: (0,5), (1, 8), (-2, -1) and (-3, -4)

Step 2 :

Graph is shown in step2.

2. ### Graph y= 2x2 - 6x + 4

Step 1 :

Given equation: y= 2x2 - 6x + 4

At x = 0
=> y = 2x2 - 6x + 4
=> y= 2(0)2 - 6(0) + 4
=> y= 4
At x = 1
=> y= 2x2 - 6x + 4
=> y= 2(1)2 - 6(1) + 4
=> y= 0
At x = -1
=> y= 2(-1)2 - 6(-1) + 4
=> y= 2 + 6 + 4
=> y = 12
At x= 2
=> y= 2(2)2 - 6(2) + 4
=> y= 8 - 12 + 4
=> y = 0

So, the coordinates are: (0, 4), (1, 0), (-1, 12) and (2, 0)
