Mathematics — first biennium · Lesson
A table, a formula and a graph describe the same function. A table row (x,y) is also a point on the graph.
In this lesson: Move between formulas, tables and graph points for simple functions.
How to proceed: Substitute x into the formula. The value obtained is y and becomes the second coordinate of the point: do not swap the order.
You can already assume: Functions, coordinates and substitution.

ConceptStep separates what is required from what is recommended or useful as reinforcement. Only required prerequisites block your progress.
Relationships: solid line = required · dashed line = recommended · dotted line = reinforcement.
