I REALLY need help :(

The table shows the outputs, y, for different inputs, x:


Input (x) 1 2 3 4

Output (y) 5 5 7 9


Part A: Do the data in this table represent a function? Justify your answer. (3 points)


Part B: Compare the data in the table with the relation f(x) = 2x − 8. Which relation has a greater value when x = 4? (2 points)


Part C: Using the relation in Part B, what is the value of x if f(x) = 34? (5 points)


I know Part A is a yes but I got 0 for part B which I'm not even sure if its correct. Even if it IS 0 I don't know how that would work for part C.

All models will perform same because we have not seen the test data. A. 1 and 3. B. 1 and 3. C. 1, 3 and 4. D. Only 5. Solution: C. The trend of the data looks like a quadratic trend over independent variable X. A higher degree (Right graph) polynomial might have a very high accuracy on the train population but is expected to fail badly on test
