Question 1 · 1 mark · Difficulty 1/3

Which of the following BEST describes a function?

  1. A relation where each element in the domain maps to exactly one element in the range
  2. A relation where each element in the range maps to exactly one element in the domain
  3. A relation where elements can map to multiple outputs
  4. A relation where all elements must map to the same output
Show answer & explanation
✓ Answer: AA relation where each element in the domain maps to exactly one element in the range
Award 1 mark for identifying that a function maps each domain element to exactly one range element. B is incorrect — this describes a one-to-one function from the range's perspective. C is incorrect — this describes a relation, not necessarily a function. D is incorrect — this describes only constant functions.
Question 2 · 1 mark · Difficulty 1/3

The function f is defined as f(x) = 2x + 3. What is f(4)?

  1. 8
  2. 11
  3. 14
  4. 7
Show answer & explanation
✓ Answer: B11
Award 1 mark for correct substitution and calculation: f(4) = 2(4) + 3 = 8 + 3 = 11. A is incorrect — this only calculates 2(4). C is incorrect — this incorrectly adds before multiplying. D is incorrect — this subtracts instead of adds.

CXC CSEC Mathematics: Relations, Functions and Graphs FAQ

How many CXC CSEC Mathematics questions on Relations, Functions and Graphs are there on Kramizo?
Kramizo currently has 275 exam-board-aligned practice questions on Relations, Functions and Graphs for CXC CSEC Mathematics, with new questions added every week. Each question gives you instant feedback and a full examiner-style mark scheme that tells you exactly what would earn marks on a real CXC paper. The questions span the full difficulty range — from straightforward recall (level 1) right up to multi-step reasoning and evaluation (level 3) — so the bank works for first-pass revision and final exam-week stress testing alike.
Is Kramizo free for CXC CSEC students preparing for Mathematics?
Yes — completely free. Every student gets 45 questions a day on the free plan, with no card required and no trial countdown. That free quota works across every subject and every topic in our bank, so you can mix Relations, Functions and Graphs practice with other Mathematics topics or even switch to a totally different CXC subject without paying anything. Kramizo's optional Pro plan removes the daily cap and adds detailed progress analytics, but the free tier is the real product — used by thousands of GCSE, IGCSE and CSEC students.
Are the Relations, Functions and Graphs questions aligned to the official CXC CSEC Mathematics syllabus?
Every question is written against the published CXC CSEC Mathematics specification, including the exact command words (state, describe, explain, calculate, evaluate, etc.), mark allocations, and difficulty tier you'd see on a real CXC paper. Explanations are written in the style of official examiner mark schemes — they tell you what is being awarded marks and why distractors are wrong, not just whether you got it right. The bank is continually refined to match the latest syllabus updates from CXC.
How is Relations, Functions and Graphs typically tested on CXC CSEC Mathematics papers?
Relations, Functions and Graphs appears across multiple question types on real CXC CSEC Mathematics papers — most commonly as multiple-choice questions in the objective section, structured short-answer questions in the main paper, and occasionally as part of an extended response. Kramizo's practice bank reflects that mix: 4-option MCQs, true/false statements, fill-in-the-blank key terms, multi-select questions, and ordering questions. Working through the bank gives you exposure to every question style examiners actually use.
