what is the cum of column 1

Question

in colum one is 1,4,7, x + 1 

Answer 1

Amber, I'm not sure of what you are asking. I'm presuming the problem is set up something like this:

   x + 1

x       y

1       ?

4       ?

7       ?

The function is x + 1. What does this mean? To each x, add 1.

If x = 1, what is y? y = 2

If x = 4, what is y? y = 5

If x = 7, what is y? y = 8

I hope this helps.
