◉Data . Answer: A collection of facts, which might be numbers, words,
measurements, observations or simply descriptions.
◉Variable . Answer: 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 . Answer: A changing variable that is measured
on a number scale; a variable with a numeric value.
◉Qualitative Variable or Categorical Variable . Answer: A variable that
is not numeric; it describes data that fits into categories.
◉Independent Variable . Answer: 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 . Answer: 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 . Answer: A quantitative variable that is chosen to find a
solution, or output, of a function.
◉Output . Answer: A quantitative variable that is produced by a function
when an input is chosen.
◉Function . Answer: 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 . Answer: A function that undoes, or reverses, the
action of another function (e.g., using multiplication to check division).
