Medal and fan!
I have no idea what to do here's the question.
The table below shows the outputs y for different inputs x:

Input
(x) 1 1 3 3
Output
(y) 4 2 12 6

Part A: Does the table represent y as a function of x? Justify your answer. (5 points)

Part B: The total cost f(x), in dollars, for renting a paddleboat for x hours is shown below:

f(x) = 20 + 10x

What is the value of f(120), and what does f(120) represent? (5 points)
