UPDATE 2024-2025
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)
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
function notation - ANSWER-✅a way to name a function that is defined by an
equation
Global Maximum - ANSWER-✅Finds the highest y-number the function goes to
Global minimum - ANSWER-✅Finds the lowest y-number the function goes to
Horizontal Asymptote - ANSWER-✅a horizontal line that the curve approaches but
never reaches
inequality - ANSWER-✅A mathematical sentence that shows the relationship
between quantities that are not equivalent
inflection point - ANSWER-✅The point on a curve at which the curves concavity
changes; also called the point of inflection
Input-output pairs - ANSWER-✅The representation of an input value and an output
value as an ordered pair, written (x,y)
Interpolation - ANSWER-✅A method of inserting new data points in the range of a
known set of data points
Interrelated causality - ANSWER-✅An output produced by the interaction of several
connected, or related, inputs
interval - ANSWER-✅A range of numbers that include all the real numbers between
its endpoints
inverse - ANSWER-✅opposite
inverse function - ANSWER-✅a function that "undoes" what the original function
does
least-squares regression method - ANSWER-✅uses all of the data to separate a
mixed cost into its fixed and variable components
linear function - ANSWER-✅A function whose graph is a straight line.
