Asymptote - ANSWER a horizontal, vertical, or slanted line that a graph
approaches but never touches
coefficient of determination - ANSWER A statistic that measures how well a
regression prediction approximates the real data points. An r^2 of 1 indicates that
the regression prediction is a perfect fit for the data
common ratio - ANSWER The number by which each term in a sequence is
multiplied to find the next number in the sequence; for example 4 is the common
ratio for the sequence [1, 4, 16, 64, 256...]
Constant ratio - ANSWER Occurs when the numeric relationship between two
quantities- that is, how many times one number contains the second- remains
unchanged over time
Data regression - ANSWER The process of examining data points to determine a
valid equation. "Regression" refers to bringing different data points down toward a
normal average- "regressing" them
,equation - ANSWER A mathematical sentence that contains an equals sign.
explanatory variable - ANSWER A variable that, as it changes, affects another
variable (called the response variable); for example, as a person pumps more gas
into a car's tank(the explanatory variable), the cost of the purchase rises (the
response variable)
order of operations - ANSWER the order in which operations in an expression to
be evaluated are carried out. 1. parentheses 2. exponets 3. multiplication and
divison 4. addition and subtraction (please excuse my dear aunt sally)
ordered pair - ANSWER A pair of numbers that give the location of a point on a x
and y grid. for example graph (3, 2)
Output Variables - ANSWER The output, represented by one or more letters, such
as m or d(t), produced by a function, based on the output variable
Polynomial - ANSWER a mathematical expression that is the sum of a number of
terms
Polynomial's degree - ANSWER The value of a polynomials largest exponent
Big Box Stores - ANSWER A very large store, typically over 50000 square feet,
of plain design, resembling a large box
Calculate the average rate of change - ANSWER The formula to compute an
average rate of change is
,quantitative variable - ANSWER a characteristic that can be measured
numerically
qualitative variable - ANSWER A variable that is not numeric; also called a
categorical variable, a qualitative variable describes data that fits into categories
response variable - ANSWER A variable that is changed by another variable
(called the explanatory variable); for example, when a person is purchasing gas,
the cost (the response variable) rises as more gas is pumped into a cars tank (the
explanatory variable).
exponent - ANSWER A mathematical notation indicating the number of times a
quantity is multiplied by itself.
exponential function - ANSWER a function of the form f(x) = ab^x, where a and b
are real numbers with a ≠ 0, b>0, and b ≠ 1
extrapolation - ANSWER the act of estimation by projecting known information
f(x)=mx+b - ANSWER linear function
f(x) = mx - ANSWER A very basic function
function - ANSWER A relation based on a set of inputs and a set of possible
outputs where each input is related to exactly one output
Equation - ANSWER A mathematical statement that two things are equal; it
consists of two expressions, one on each side of an equals sign.
, 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.
