- Evaluate a function for a given input.
- Find inputs, outputs, and compositions.
- Explore domains, inverses, and intercepts.
Worked example
For f(x) = 2x + 3, f(4) = 2 × 4 + 3 = 11. To find the input giving 11, solve 2x + 3 = 11: x = 4.
How the Ladder Works
Six levels run from Warm-Up to Mastery. Warm-Up has five questions; later sets grow to eight or nine depending on the topic. Clear a level with at least 80% first-try accuracy. Every level is available from the start, and retries produce fresh questions.
Hints and worked solutions support practice. Grades 8–11 is a guide, not a restriction.
