It's the first one. Note that for each unit increase in x, y increases by 1/2:
outputs are 1/2, 2/2, 3/2, 4/2, corresponding to 1, 2, 3 and 4 as inputs.

Answer:
920*1.12^t
Step-by-step explanation:
Every year, we see that it goes up 12%.
12% in decimal form is 0.12.
Let's say we have "x" amount of cars one year. The next year, the number of cars will increase by 12%. 0.12x is added on after one year.
So in total, at the beginning of a new year, the number of cars is 0.12x+x = 1.12x.
In this case, we have 920 cars. So if every year the number of cars is multiplied by 1.12, then in "t" years we will have 920*(1.12)^t. We multiply by 920 because that's the current number of cars, and we add the ^t because we multiply by 1.12 every year.
You are very welcome!
