Definitions A function is a rule which associates each member of a set, A, the domain a unique element of a set, B, the range Composite functions If then is a composite function. Function is calculated first on and function is calculated on the result. Function diagram Range Domain Natural Domain This is the set of all real numbers that can be used in a function Points to note: One-to-one Functions/ inverses A B A B A one-to-one function has an inverse If then rearrange to write. Interchanging and gives. Graph of a Function Domain [a,b]= Range [d,e] Foundations Functions Index page

Modulus Function Linear function Quadratic function Polynomial functions If the degree of the polynomial is i.e. where and are polynomials. is a proper fraction if Otherwise the fraction is improper. Rational functions Odd & Even Functions A function is even if A function is odd if The graph of an odd function has rotation symmetry about the origin and that of an even function has reflection symmetry in the axis.

Quadratic Factorise or use Polynomial: Remainder theorem & Factor Theorem If is a factor of If then the remainder when is divided by is Exponential 1 Exponential 2 Simultaneous –non linear Try: 1)Solve one equation for (or ) in terms of or for (or ) in terms of and substitute in the other equation 2)Factorise or and set the factors equal to zero.
