Question

For the following function, how do I construct a table. `y=3x; and -3<=x<=4`?

Ask for table (y):
X | Y |
-3 | |
-2 | |
-1 | |
0 | |
1 | |
2 | |
3 | |
4 | |

sorry I don't know how to draw a table here. Thank you

Answer 1

Please refer to the attached table of values.

Explanation:

Lets calculate the values of y by substituting values of x which satisfy `-3<= x <=4`.

Attached is the table, please check thoroughly.

Hope this helps!

Answer 2

Choose an `x` value and multiply by `3` to get `y`

Explanation:

You are given two separate pieces of information.

`y = 3x` tells you that the value of `y` is obtained by multiplying an `x` value by `3`

The inequality tells you that you can use values of `x` from `-3` to `4`

So take an `x` value, multiply by `3` and that is the value for `y`

`y = 3(-3) = -9`
`y = 3(-2) = -6`
`y = 3(-1) = -3`

and so on..

This will give:

`x: -3" "-2" "-1" "0" "1" "2" "3" "4`
`y:-9" "-6" "-3" "0" "3" "6" "9" "12`
