◉ exponential function.
Answer: 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.
Answer: A method of inserting new data points outside the range of
a known set of data points. ("Extra" means outside.)
◉ f(x) = mx.
Answer: 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.
Answer: 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.
, 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: The conventional way to write a function, precise enough to
describe the function without a long written explanation.
◉ function of best fit.
Answer: A function that best represents given data points.
◉ functions.
Answer: A relation based on a set of inputs and a set of possible
outputs where each input is related to exactly one output.
◉ general trend.
Answer: A pattern of gradual change in a consistent direction,
represented by a line or curve on a graph.
◉ global maximum.
Answer: The maximum over the entire range of a function.
◉ global minimum.
Answer: The minimum over the entire range of a function.
