Generate a table of values from graph

Lesson

Remember that every graph has an $X$X-axis and a $Y$Y-axis.

The numbers on the $X$X-axis are sometimes called the inputs, while the numbers on the $Y$Y-axis are called the outputs.

We're going to practice completing tables of inputs and outputs given a graph.

Worked Example

Question 1

Given the following graph, fill in the table.

$X$X $2$2 $4$4 $6$6 $8$8 $10$10 $12$12 $14$14 $16$16
$Y$Y                

 

 

Notice on the graph that when the input $X$X is $2$2, the output $Y$Y is $1$1.

We can fill this output in the table.

$X$X $2$2 $4$4 $6$6 $8$8 $10$10 $12$12 $14$14 $16$16
$Y$Y $1$1              

We can use this method to fill in the entire table like so.

$X$X $2$2 $4$4 $6$6 $8$8 $10$10 $12$12 $14$14 $16$16
$Y$Y $1$1 $2$2 $3$3 $4$4 $5$5 $6$6 $7$7 $8$8

Further Examples

Question 2

Given the following graph, fill in the table.

Loading Graph...

  1. $x$x $1$1 $2$2 $3$3 $4$4
    $y$y $\editable{}$ $\editable{}$ $\editable{}$ $\editable{}$

Question 3

Buzz recorded his savings (in $dollars$dollars) over a few months in the graph given.
