Answer:

I think is f(n) = 3 + 3(n - 1)

Step-by-step explanation:

Because it goes up 3 in price and 1 in gallons of gas

Answer:

f(n) = 3+3(n-3)

Step-by-step explanation:

We can first notice that the slope is 3 and a y intercept of 0. So, we can just simplify all the equations

f(n) = 4+3(n-1)

f(n) = 4+3n-3

f(n) = 3n+1

y=3x+1

No

f(n) = 3+5(n-1)

f(n) = 3+5n-5

y=5x-2

No

f(n) = 2+3(n-1)

f(n) = 2+3n-3

y=3x-1

No

f(n) = 3+3(n-1)

f(n) = 3+3n-3

Yes

y=3x
