The relation between input and output is defined by Function, if the input of the function changes, then its resultant has also changed. Function Calculator is a input output calculator that will help us to graph a function. It is a linear function calculator if the input is a quadratic function, then it calculates the x-intercept, y-intercept and vertex. If the input is linear function, then it calculates the x-intercept, y-intercept and slope. It called as function tables input output calculator.

Below is given a default function, click "Graph". It calculates x-intercept, y-intercept, slope and then plot the graph.

Step 1 :  

Observe the given linear function.



Step 2 :  

Plug in different values for x and find the value for y and then list all the coordinates and plot it on graph.

  1. Plot the graph for the function: f(x) = 2x + 1


    Step 1 :  

    Given function: f(x) = y = 2x + 1



    Step 2 :  

    if x = 0, then


    y = 2(0) + 1 = 1


    y = 1


     


    if x = 1, then


    y = 2(1) + 1 = 3


    y = 3


     


    if x = 2, then


    y = 2(2) + 1 = 5


    y = 5


     


    if x = -1, then


    y = 2(-1) + 1 = -1


    y = -1


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

  2. Plot the graph for the function: f(x) = x + 12


    Step 1 :  

    Given function: f(x) = y = x + 12



    Step 2 :  

    if x = -10, then


    y = -10 + 12 = 2


    y = 2


     


    if x = 10, the


    y = 10 + 12 = 22


    y = 22


     


    if x = 20, then


    y = 20 + 12 = 32


    y = 32


     


    if x = 30, then


    y = 30 + 12 = 42


    y = 42


    So, the coordinates are (-10, 2) (10, 22), (20, 32) and (30, 42)
