Algebra 1 · Functions & Sequences
Definition
The input is the x-value fed into a function and the output is the resulting y-value.
Teach it
Where it is taught, with guided notes, practice, homework, an exit ticket and an interactive Teacher Deck.
Examples
- Input x = 3 with rule 2x + 1 gives output 7.
- Input x = 0 with rule x − 4 gives output −4.
Key rule
Apply the rule to the input to produce the output.
Memory hook
Input goes in, rule runs, output comes out.
