How do I know if it is a MAXIMUM or MINIMUM point?

Differentiate again to find d^2y/dx^2 (the second derivative).--> if SMALLER than 0 it is a MAXIMUM POINT --> if BIGGER than 0 it is a MINIMUM POINT

Types of Geometrical Transformations?

3 types: Translations (write as vectors!), Stretches, Reflections. Horizontal movements are inside brackets. Vertical movements are outside of brackets :)

Remainder Theorem

sub in the number to the polynomial :) e.g. f(2)=(2x8)-(3x4)-(3x2)+7=5 --> remainder = 5 :D
