I am having problems trying to create a table of values. Divide by 3, then add 1:x 3+1

It sounds like for each x, you want to compute y = (x/3) + 1 , and make up a table of value for a range of values of x.

That is not what you wrote, however. You wrote < x 3+1 >. I don't know what that is supposed to men

if x = 3, then y = 2
if x = 9, y = 4 , etc
