Functions | Characteristics | TG | Table |
---|---|---|---|
Linear and quadratic functions | As x grows larger, y grows larger, i.e. the graph line runs from lower left to upper right. | * | * |
Linear function | Plots distribute linearly. | * | |
The ratio of y to x is mostly constant. | * | ||
Differences between neighbouring y values are mostly constant. | * | ||
Quadratic function | Plots approach the x axis (i.e. y values approach zero) as x values become close to zero. | * | |
As x grows larger, the ratio of y to x grows larger. | * | ||
Differences between neighbouring y values become larger as x grows larger. | * | ||
Inverse Proportion | Plots approach the x axis (i.e. y values approach zero) as x becomes larger. | * | |
As x grows larger, y grows smaller. | * | * | |
Y is very large when x is close to zero. | * | ||
Differences between neighbouring y values are very large when x is close to zero. | * | ||
Differences between neighbouring y values become smaller as x grows larger. | * | ||
Non-correlated | Plots distribute randomly. | * | |
It felt as if there were multiple grahps or it were a circle. | * | ||
Differences between neighbouring y values are unstable. | * |
