How do you write a quadratic function from a table

Create the equations by substituting the ordered pair for each point into the general form of the quadratic equation, ax^2 + bx + c. ... Finally, substitute the values you found for a, b and c into the general equation to generate the equation for your parabola. Select three ordered pairs from the table.

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
