Pre-Calculus Terms Crossword

A function is defined at a given value of the independent variable if it assigns that input an output; defined means "takes on a value".
The set of all inputs for which a function or relation is defined.
A function f is even if f (x) = f (- x) .
The test by which it is shown whether a function is a one-to-one function or not, and therefore whether its inverse is a function.
A function f is odd if f (x) = - f (- x)
A function is undefined at a given value of its independent variable if for that value, there is no output--this occurs when a particular input creates a situation in which there is division by zero, or an even root of a negative number, for example.
The test by which a relation is either shown to be a function or not. The graph of a function does not intersect with a vertical line more than once.
A function is piecewise if and only if it uses different rules for different parts of its domain
A function is periodic if and only if f (x) = f (x + c) , for all values x , where c is a constant. A periodic function repeats itself at regular intervals.
A function is one-to-one if each element in its range is paired with exactly one element from its domain.
A relation which assigns a correspondence from the elements of the range to those of the domain. The inverse of a function or relation can be found by interchanging the variables in the function or relation.
The set of all possible ordered pairs (a, b) composed of elements taken from the two sets, A and B .
A line that a graph approaches but never crosses
when a<1 and the graph is stretched along the x-axis
