Mathematics Standards, August 2008, 0SPI
approximate - To obtain a number close to an exact amount.
arithmetic sequence - A set of numbers in which the difference between any
two consecutive numbers is the same.
binomial – A polynomial with two terms.
completing the square - A method used to solve a quadratic equation when
factoring is possible, but the factors are not immediately obvious.
consecutive - In order, with none missing.
constant - A quantity that always stays the same.
correlation, negative - A relationship between two sets of numerical data in
which one set generally increases as the other decreases.
correlation, positive - Two sets of data where the numbers in one set tend
to increase, then the numbers in the other set tend to increase.
correlation, strong - A regular pattern emerges when looking for a
relationship between two set of data.
correlation, weak - No regular pattern emerges when looking for a
relationship between two set of data.
cube (exponent) - The third power.
cube root - A number whose cube is equal to a given number.
direct proportion/ directly proportional - Two quantities that always have
the same ratio. In y=kx where k is a constant, y is directly proportional to
x.
direct variation - Direct proportion/ directly proportional.
domain - In a function, f(x), the possible values for x in the given situation.
exponential equation - The equation y=ax for a(greater than 0 but not equal
to 1) and exponent, x.
frequency - The number of times something occurs in an interval or set of
data.
geometric sequence - A sequence of terms in which each term is created by
multiplying the previous term by a constant.
intersection - To meet or cross.
inverse proportion/ inversely proportional - Two variables whose products
are always the same. xy=2
inverse variation - Where two variables are inversely proportional.
line that fits the data - A line, segment, or ray drawn on a scatter plot to
estimate the relationship between two sets of data.
line, point-slope form - The equation of a line in the form y-y1=m(x-x1)
where m represents the slope of the line and (x1 y1) is a known point on
the line.
line, slope-intercept form - y=mx+b, where m is the slope and b is the yintercept.
line, standard form - ax+bx+c = 0, where a, b, and c are integers and a >
0.
monomial - the product of constants and variables (26r3s4).
nonnegative - A number that is positive or zero.
nonzero - Not zero, a number that is positive or negative.
precision - An indication of how finely a measurement was made; related to
the unit of measurement and the calibration of the tool.
polynomial - The sum of monomials.
quadrant - One of the four sections of a coordinate grid that are separated
by axes.
quadratic equation - A polynomial equation containing one or more terms in
which the variable is raised to be the second power but no higher.
quadratic formula - Formula used to solve any quadratic equation: If ax2 +
bx + c = 0 and a = 0, then
quadratic function - A function with a second degree variable.
radical - A symbol that indicates the root to be taken (
).
range - The possible values for y in an equation.
rate of change - The ratio of change in one quantity to the corresponding
change in another quantity.
real number - The combined set of the rational and irrational numbers.
recursive (sequence, series) - Each term is determined by application of a
formula to preceding terms.
region- A part of plane.
root - The inverse of a power (In ax=b, a is the xth root of b).
sequence - An order set of objects or numbers.
solution set - The set of values that make an equation or inequality true.
square (exponent) - The second power.
system - Two or more related linear equations (or inequalities) for which
you seek a common solution.
term - Parts of an expression or series separated by a plus or minus, or
parts of a sequence when separated by commas.
trinomial - A polynomial with three terms.
valid - true
variable, dependent - A variable thatdepends on one or more other
variables. For equations such as y=3x-2, the dependent variable is y.
variable, independent - A variable in an equation that may have its value
freely chosen without considering values of any other variable.
