Only focus on the part where the power is a positive integers. You can skip the parts where the powers are negatives or fractional.

For sum of infinite GP, it can only happen when -1 < r < 1. This means the series is converging (it sums to a finite value).

For r > 1 or r < -1, this means is series is diverging (it will not sum to a finite value). Hence, you cannot use sum to infinity formula for it.

We use the vertex form of a quadratic to:

1) Find max/min coordinate (vertex)
2) Find the equation of the line of symmetry (x = a)
3) Solve for x (finding roots)
4) To find the inverse of a quadratic function (Need to choose +/- version)
