Equation A mathematical statement that two things are equal; it consists
of two expressions, one on each side of an equals sign.
Data A collection of facts, which might be numbers, words,
measurements, observations or simply descriptions.
Variable Something that can vary, often used in equations, and usually
represented by a letter (e.g., t for time, n for number, c for
color).
Quantitative Variable A changing variable that is measured on a number scale; a
variable with a numeric value.
Qualitative Variable or Categorical Variable A variable that is not numeric; it describes data that fits into
categories.
, Independent Variable A variable that, as it changes, affects another variable (called
the dependent variable). For example, as gas (the
independent variable) is pumped into a car's tank, the cost of
the purchase (the dependent variable) rises. The input of a
function.
Dependent Variable A variable that is changed by another variable (called the
independent variable). For example, when purchasing gas, the
cost (dependent variable) rises as more gas (the independent
variable) is pumped into the car's tank. Dependent variables
are usually drawn on the y-axis of a graph. The output of a
function.
Input A quantitative variable that is chosen to find a solution, or
output, of a function.
Output A quantitative variable that is produced by a function when an
input is chosen.
Function A mathematical relationship between two variables where
every input is matched with exactly one output value.
y = f(x)
Format: Dependent Variable (Independent Variable)
This is not a multiplication equation; it is read as "the value of f
at x" or "for a given input of x, what is the function's output?"
Inverse Function A function that undoes, or reverses, the action of another
function (e.g., using multiplication to check division).
The inverse of f(x) is written f^-1(x) and read "f inverse of x."
Graph A diagram showing the relationship between variable
quantities on two axes drawn at right angles.
x,y
Independent Variable, Dependent Variable
Origin On a graph, the starting point where both x and y are equal to
zero, and the x-axis and the y-axis intersect.
Interval A range of numbers that include all the real numbers between
its endpoints.
Inequality An expression that compares two numerical values when they
are not equal.
Profit A financial gain when the amount of revenue from a business
entity exceeds the expenses, costs, and taxes needed to
maintain the business activity.
Output Variable The output, represented by one or more letters, such as m or
d(t), produced by a function, based on the input variable.
Table In math, a logical arrangement of quantitative data in columns
and rows.
Trends A pattern of change in a condition or process, often
represented by a line or a curve on a graph.
