Answer 1

Answer: Quadratic

Explanation:

1. The function can't be linear because the y goes down and up.

2. The function can't be constant because the y decreases and increases, instead of only increasing or decreasing.

3. The function can't be a exponential function because the value of y decreases and increases.

4. The only type that the function can be is quadratic.
