Get down with the lingo
Empty SetA set containing no elements.
DomainAll the values x can take in a function. It's like x is a little king, and the domain is, well, its domain.
RangeThis is the set of all possible outputs of a function. It's generally the possible y-values. It has very little to do with the Lone Ranger or free range chickens.
FunctionA relation between sets of input and output where each input is related to one and only one output. The lobster model of mathematics.
GraphA diagram representing data or relationship(s) between variables.
Ordered PairTwo numbers written in a certain order; (a, b) is different from (b, a).
Independent VariableA variable that assume values freely, or independently, in a function.
InterceptThe point where the graph of a function crosses the x-axis or y-axis.
SlopeThe steepness of a line, calculated as rise over run; think skiing (the bunny slope is less steep than the triple black diamond).
Quadratic EquationAn equation obtained by setting a quadratic polynomial to 0.
Quadratic PolynomialA polynomial of degree 2.
Exponential FunctionA function of the form y = abx + c. Their graphs form a nice, smooth curve.
InequalityA mathematical statement using the symbols <, >, ≤, ≥.
