Hi, seems like the answer is f(x) = x - 4 Edit: this was my original answer, but I was apparently completely out of my mind when I wrote it. The correct answer is f(x) = -4x + 50, as I stated below. I'm very sorry for any trouble I caused
ok yay then lol.

S = 50-4t

Proof:

S = 50 - 4t
30 = 50 - 4(5)
30 = 50 - 20
30 = 30

S = 50 - 4t
34 = 50 - 4(4)
34 = 50 - 16
34 = 34

Don't ask how I got it lol
