Domain
Is the set of first coordinates of the ordered pair of a relation
Function
Is a relationship in which each member of the domain is paired with exactly one member of the range. A number of the domain is an input and the related number of the range is an output
Function notation
Is notation that represents a function as f(x) instead of y
Function rule
Is an equation that describes a function
Linear equations
Is any equation whose graph is a line
Linear inequality
Is a number sentence in which the equal sign of a linear equation is replaced with <,>
