A straight line on a graph showing the best possible match for the data; also called a
"trend line."

1 asymptote 2 line of best fit
3 equations 4 calculate the average rate of change
Don't know?
Terms in this set (87)
asymptote A horizontal, vertical, or slanted line on a graph that a curve
approaches but never touches.
average rate of change The average rate at which one variable is changing in relation
to another variable's changing.
big-box stores A very large store, typically over 50,000 square feet, of plain
design, resembling a large box.
broadband High-speed Internet access that is always on and much faster
than dial-up.
calculate the average rate of change The formula to compute an average rate of change is (y2-y1)
divided by (x2-x1).
, coefficient of determination A statistic that measures how well a regression predictions
approximate the real data points. An r^2 of 1 indicates that the
regression prediction is a perfect fit for the data.
common era A designation previously called "A.D.," meaning annus domini,
"year of the Lord"; the Common Era dates year 1 as the
presumed year of Jesus of Nazareth's birth.
common ratio 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 Occurs when the numeric relationship between two quantities
- that is, how many times one number contains the second -
remains unchanged over time.
data A collection of facts, which might be numbers, words,
measurements, observations or simply descriptions.
data regression 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.
dependent variable A variable that is changed by another variable (called the
independent variable); for example, when a person is
purchasing gas, the cost (the dependent variable) rises as
more gas is pumped into a car's tank (the independent
variable).
equations A mathematical statement that two things are equal; it consists
of two expressions, one on each side of an equals sign.
exponent A mathematical notation - a superscript - that defines the
number of times a number is multiplied by itself.
exponential function A function that has an extremely rapid increase or decrease in
quantity in proportion to its current value; its form is f(x) = b^2.
extrapolation A method of inserting new data points outside the range of a
known set of data points. ("Extra" means outside.)
f(x) = mx A very basic function; it means that the function of x is the
product of a constant multiplied by a variable input, x.
f(x) = mx +b A basic common function; it means that the function of x is the
product of a constant multiplied by a variable input, x, plus
another constant, b.
function 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 The conventional way to write a function, precise enough to
describe the function without a long written explanation.
function of best fit A function that best represents given data points.
functions A relation based on a set of inputs and a set of possible
outputs where each input is related to exactly one output.
