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

Please refer to the attached table of values.enter image source here

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!

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
