Representation
8.F.A.2
Definition
A way of showing a function, such as a verbal description, an equation, a table, or a graph. Different representations of the same function are equivalent.
Examples
- 'Output is one more than twice the input' describes the same function as f(x) = 2x + 1.
- A table and a graph can represent the exact same rule.
Key rule
You can translate between words, equations, tables, and graphs — they describe the same rule.
Memory hook
