Terms in this set (28)
element
each value in a matrix
empty set
a set with no elements
finite set
a set with a definite number of elements
infinite set
a set with an unlimited number of elements
interval notation
a way of writing the set of all real numbers between two endpoints. The symbols [ and ] are used to include an endpoint in an interval, and the symbols ( and ) are used to exclude an endpoint from an interval.
roster notation
a way of representing a set by listing the elements between braces, {}.
set
a collection of items called elements
set-bulider notation
a notation for a set that uses a rule to describe the properties of the elements of the set.
subset
a set that is contained entirely within another set.
like radical terms
terms having the same radicand and index
principal root
the positive square of a number, indicated by the radicand sign.
radical symbol
the symbol
square root
used to denote a root.
radicand
the number or expression under a radical sign.
rationalizing the denominator
a method of rewriting a fraction my multiplying by another fraction that is equvalent to 1 in order to remove radical terms from the denominator.
scientific notation
a method of writing very large or very small numbers, by using powers of 10 in the form m x 10^n, where 1 is less than or equal to m, which is less than 10 and n is an interger.
domain
the set of input vaules of a function or relation.
range
the set of output values of a function or relation.
function
a type of relation that pairs each element in the domain with exactly one element in the range.
relation
a set of ordered pairs.
independent variable
the input of a function; a variable whose value determine the value of the output
dependent variable
the output of a function; a variable whose value depends on the value of the input
function notation
if x is the independent variable and y is the dependent variable, than the funtion notation for y id f(x).
compression
a transformation that pushes the points of a graph horizonatally toward the y-axis or vertically toward the x-axis.
reflection
a transformation across a line that reflects. it is the perpendicular bisector of each segment joining a point and its image
stretch
a transformation that pulls the points of a graph horizontally away from the y-axis or vertically away from the x-axis.
transformation
a change in the position, size, or shape of a figure
translation
a transformation in which all the points of a figure move the same distance in the same direction
parent function
the most basic function of a family of functions, pr the original function before a transformation is applied.
