monomial
an expression with only one term
domain
The set of x-coordinates of the set of points on a graph; the set of x-coordinates of a given set of ordered pairs. The value that is the input in a function or relation.
range
The y-coordinates of the set of points on a graph. Also, the y-coordinates of a given set of ordered pairs. The range is the output in a function or a relation.
linear equation
an equation whose solutions form a straight line on a coordinate plane.
vertex
the point of intersection of the two rays that form the sides of the angle
intercept
the point at which a line intersects a coordinate axis
axis of symmetry
A line that divides a figure in half so that each half is the mirror image of the other
integer
The set of whole numbers and their opposites
absolute value
The distance a number is from zero on a number line
intersecting lines
Lines that cross at exactly one point
polynomial
a mathematical expression that is the sum of a number of terms
cordinate plane
- formed by two real number lines that intersect at a right angle
ordered pair
A pair of numbers, (x, y), that indicate the position of a point on a Cartesian plane.
square number
The product of a number multiplied by itself.
function
a mathematical relation such that each element of one set is associated with at least one element of another set
combine like terms
to add or subtract like terms. Ex: 3x and- 5x combine to become -2x.
constant difference
the difference that is always the same from one term to the next number
algebraic expression
A mathematical phrase involving at least one variable and sometimes numbers and operation symbols.
exponent
a mathematical notation indicating the number of times a quantity is multiplied by itself
term
any distinct quantity contained in a polynomial
maximum
the point on a curve where the tangent changes from positive on the left to negative on the right
minimum
the point on a curve where the tangent changes from negative on the left to positive on the right
slope
the steepness of a line on a graph, equal to its vertical change divided by its horizontal change
variable
a symbol (like x or y) that is used in mathematical or logical expressions to represent a variable quantity
negative exponent
an exponent less than zero which causes the base and its exponent to move positions in a fraction
