Write a rule for the linear function in the table (1)()()()(0)

Here, f(x) = {(1,3), (2,2), (3,1), (4,0)}
So, rule for this function is {x+n, y-n}

Where, n = number of steps, & x, y are the initial values of the function which is 1 & 3 respectively

Hope it Helped

Y= -x + 4
I just did this one. Look at the steps I. The other one.

Hey dear, hoping i'll be
