Key Calculus Terms and definitions covered in this textbook
• Binomial theorem

A theorem that gives an expansion formula for (a + b)n

• Bounded above

A function is bounded above if there is a number B such that ƒ(x) ? B for all x in the domain of ƒ.

• Closed interval

An interval that includes its endpoints

• Coefficient of determination

The number r2 or R2 that measures how well a regression curve fits the data

• Cotangent

The function y = cot x

• Data

Facts collected for statistical purposes (singular form is datum)

• Division

a b = aa 1 b b, b Z 0

• Even function

A function whose graph is symmetric about the y-axis for all x in the domain of ƒ.

• Graph of a function ƒ

The set of all points in the coordinate plane corresponding to the pairs (x, ƒ(x)) for x in the domain of ƒ.

• Horizontal asymptote

The line is a horizontal asymptote of the graph of a function ƒ if lim x:- q ƒ(x) = or lim x: q ƒ(x) = b

• Hyperboloid of revolution

A surface generated by rotating a hyperbola about its transverse axis, p. 607.

• Increasing on an interval

A function ƒ is increasing on an interval I if, for any two points in I, a positive change in x results in a positive change in.

a + 1-a2 = 0, a # 1a

• Negative association

A relationship between two variables in which higher values of one variable are generally associated with lower values of the other variable.

• Rational numbers

Numbers that can be written as a/b, where a and b are integers, and b ? 0.
