Which quadratic function is represented by the table?

Since we know that the function of the table is a quadratic function, we can start writing this function as follows:

Given that we have three variables , we can solve this problem by taking three points, say:

So these points must satisfy the equation of the function. Therefore:

So we have two equations to solve for a and b:

So the quadratic function represented by the table is:
