Functions and Graphs — JAMB Mathematics Past Questions
Functions and Graphs is one topic inside the JAMB Mathematics syllabus, and drilling it on its own is usually faster than revising the whole subject again. Below: which JAMB years have examined it, then real Functions and Graphs questions with worked answers.
When JAMB examined Functions and Graphs
Functions and Graphs questions appear in our bank for the JAMB years below. This is taken from the questions themselves, not from a syllabus outline — so if a year is listed, this topic was genuinely examined that year.
A topic that keeps reappearing is a topic JAMB keeps testing. Newer years matter most, because question style drifts.

Given that f(x) is one-to-one, find the inverse of the function f(x) = (2x + 3).
- A x + 3 / 2
- B x − 3 / 2
- C 3 − x / 2
- D x + 3
Answer: B
To find the inverse: let y = 2x + 3 → solve for x: x = (y − 3)/2 → f⁻¹(x) = (x − 3)/2.
If f(x) = x² + 4, then f(1) =
- A \(x^2 + 4\)
- B \(x^2 - 4\)
- C \(5\)
- D \(4x - 2\)
Answer and full explanation are inside the app.
Check the answerIf f(x) = x - 4, then f(f(3)) =
- A \(3\)
- B \(-5\)
- C \(2\)
- D \(1\)
