You give some value to x.
Then you calculate the corresponding value of the function f(x), using the formula.


Then you give some other value to x.
Then you calculate the corresponding value of the function f(x), using the formula.


Then you give some other value to x.
Then you calculate the corresponding value of the function f(x), using the formula.


You write the values of x into the left column of the table.
You write the calculated values of the function into the right column of the table.


In this way, you obtain the Table of values of the function, after repeating these steps several times.


It is the first part of the work.

Is everything clear to you in my description so far ?



Then the next stage comes.

You take a page of a graph paper and a pen (or a pencil).

You accurately mark every pair of numbers from your Table as a point on a graph paper.


Then you connect the plotted points, using your pen or pencil.


Is everything clear to you in this stage ? ?
