Constant function (on an interval)
ƒ(x 1) = ƒ(x 2) x for any x1 and x2 (in the interval)

Descriptive statistics
The gathering and processing of numerical information

Direction vector for a line
A vector in the direction of a line in threedimensional space

Even function
A function whose graph is symmetric about the yaxis for all x in the domain of ƒ.

Inverse cosine function
The function y = cos1 x

Inverse properties
a + 1a2 = 0, a # 1a

Linear correlation
A scatter plot with points clustered along a line. Correlation is positive if the slope is positive and negative if the slope is negative

Linear function

Onetoone rule of logarithms
x = y if and only if logb x = logb y.

Product of functions
(ƒg)(x) = ƒ(x)g(x)

Quantitative variable
A variable (in statistics) that takes on numerical values for a characteristic being measured.

Sample standard deviation
The standard deviation computed using only a sample of the entire population.

Solve algebraically
Use an algebraic method, including paper and pencil manipulation and obvious mental work, with no calculator or grapher use. When appropriate, the final exact solution may be approximated by a calculator

Symmetric matrix
A matrix A = [aij] with the property aij = aji for all i and j

Triangular form
A special form for a system of linear equations that facilitates finding the solution.

Triangular number
A number that is a sum of the arithmetic series 1 + 2 + 3 + ... + n for some natural number n.

Variance
The square of the standard deviation.

Vertical translation
A shift of a graph up or down.

Work
