geometric sequence

Front

a sequence in which each term is found by multiplying the previous term by the same number

Back

arithmetic sequence

Front

a sequence in which each term is found by adding the same number to the previous term

Back

logarithmic function

Front

a function of the form f(x)=logbX, where b≠1 and b>0, which is the inverse of the exponential function f(x)=b^X

Back

univariate analysis

Front

the use of statistical tests to provide information about one variable

Back

Reciprocal Function

Front

D: (-∞,+∞) x can't be zero R: (-∞,+∞) y can't be zero

Back

exponential function

Front

a function that can be described by an equation of the form y= a*b^x, where b > 0 and b ≠ 1

Back

sigma notation

Front

A form of notation using the symbol Sigma, E, to express a series.

Back

measures of dispersion

Front

range, variance, standard deviation

Back

Quadratic Formula

Front

[-b ± √(b² - 4ac)] / (2a)

Back

Pascal's Triangle

Front

an arrangement of the values of nCr in a triangular pattern where each row corresponds to a value of n

Back

scatter diagram (scatterplot)

Front

a graph that shows the relationship between two quantitative variables measured on the same individual

Back

Combined Events

Front

For events E and F: • not E = P(not E) = 1 - P(E) • E or F = P(E or F) = P(E) + P(F) - P(E and F) • E and F = P(E and F) = P(E)P(F)

Back

measures of central tendency

Front

mode, median, mean

Back

rational function

Front

has 2 graphs (parabolas) and asymptotes (a line that a graph approaches, but does not intersect)

Back

interval notation

Front

A notation for describing an interval on a number line. The interval's endpoint(s) are given, and a parenthesis or bracket is used to indicate whether each endpoint is included in the interval.
