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
f(n) = 3+3(n-3)
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
f(n) = 2+3(n-1)
f(n) = 2+3n-3
y=3x-1
f(n) = 3+3(n-1)
f(n) = 3+3n-3
Yes
y=3x
