Line of best fit - roughly equal number of points/dots on each side of the line. Ignore outliers.

Ah, this is where all my 'valuable' 3U training comes in handy (it's so weird to have a lack of algebra in General, I can like, understand everything...it's in english...how weird...)

QUADRATIC: Also known as a pronumeral. Smiley face! A "happy" smile is indicated by a positive x to the power of 2 value, whilst a sad smile is a negative.

CUBIC: Cubes are normally to the power of three and this is no different.

HYPERBOLA/EXPONENTIAL: See piccy.
