4. Curriculum Content3. Functions—Core curriculum Notes / Examples3.1 Use function notation.Knowledge of domain and range.Mapping diagrams.3.2 Understand and explain that the graph of anequation in two variables is the set of all itssolutions plotted in the co-ordinate plane.Understand that a function assigns to eachelement of the domain exactly one elementof the range. If f is a function and x is anelement of its domain then f(x) denotes theoutput of f corresponding to the input of x.Construct tables of values for functions of the formax + b, ± x 2 + ax + b, xa (x ¸ 0) where a and b areintegral constants; draw and interpret such graphs.Solve associated equations approximately bygraphical methods.3.3 Write a function that describes a relationshipbetween two quantities.e.g., C(x) = 50,000 + 400x models thecost of producing x wheelchairs. Write afunction that represents the cost of onewheelchair.3.4 Extended Curriculum only.Cambridge IGCSE Mathematics (US) 0444. For examination in 2013.16
