I need help determining is a function is linear or quadratic or exponential

Given:
The table values of a function are given.
To determine:
The type of function.
Explanation:
Let us check the y values.
Since some of the y-coordinates has negative values.
So, it must not be the exponential function.
The x-coordinates are written in increasing order.
The corresponding y-values are in neither increasing nor decreasing order.
So, it must not be linear.
Hence, it must be a quadratic type.
Therefore, the function is of a type quadratic function.
Final answer:
Quadratic function.
