Excel AS Pure Mathematics terms
and their correct answers for 2024
candidates
1. Domain - Correct Answers the set of possible inputs for a function.
2. Range - Correct Answers the set of possible outputs of a function.
3. Discriminant - Correct Answers b² - 4ac > 0 then two distinct real
roots.
4. b² - 4ac = 0 then one repeated real root.
5. b² - 4ac < 0 then a quadratic function has no real roots.
6. Types of Lines for Regions - Correct Answers If y < f(x) or y > f(x)
then the curve y = f(x) is not included in the region, and is
represented by a dotted line.
7. If y ≤ f(x) or y ≥ f(x) then the curve y = f(x) is included in the region,
and is represented by a solid line.
8. Graph Translations - Correct Answers y = f(x) + a is a translation of
the graph y = f(x) by an upwards.
9. y = f(x + a) is a translation of the graph y = f(x) by a to the left.
10. Graph Stretches - Correct Answers y = aft(x) is a stretch of the
graph y = f(x) by a scale factor of a in the vertical direction.
