A:linear

B:quadratic

C:exponential

Answer 1

exponential

Explanation:

just did the quiz

Answer 2

A. Quadratic.

Explanation:

The model will better fit into a quadratic one. We can tell by seeing the numbers. To be a lineal model, there should be a proportion, which is the line graph of this type of function, being that proportion the slope.

To be an exponential model, the values should be decreasing really fast, that behaviour belong to a exponential function.

So, that's why should be a quadratic model, because is decreasing but with out a lineal proportion, and without an exponential behaviour.
