What is the quadratic function of a graph if the points are (-2, -4) (-1, -2.5) (0, 0) (1, 3.5) (2, 8)?
It can be guessed since we deal with easy numbers, but let's approach this problem theoretically.
Let's use three points out of 5 given to determine these three coefficients.
Equations (1), (2) and (3) constitute a system of 3 linear equations with three unknown variables. Let's solve it by substitution.
All we have to do is to check that two other points specified in the problem lie on this graph.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
