Since you did not include the choices to select the correct table, I will 1) explain you how to creat a table, and 2) create a table w hich which you migh compare with your choices:

1) How to make a table

For the function y = x + 4, the variable x is the input and the variable y is the output.

A table consists of a sequence of pairs x, y.

You choose the x-values and calculate th y-values using the function.

For expample if you choose x = 3 as your input, then the output is given by the function y = x + 4, so you subsititute x = 3 and obtain y = 3 + 4 = 7.

And the table is represented as in the example below.

What you have to do is checking if all the values of the table given satisfy the equation y = x + 4.


2) Table (example):

x y = x + 4
