Census
An observational study that gathers data from an entire population

Convergence of a series
A series aqk=1 ak converges to a sum S if imn: q ank=1ak = S

Dependent variable
Variable representing the range value of a function (usually y)

Graph of parametric equations
The set of all points in the coordinate plane corresponding to the ordered pairs determined by the parametric equations.

Histogram
A graph that visually represents the information in a frequency table using rectangular areas proportional to the frequencies.

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

Integers
The numbers . . ., 3, 2, 1, 0,1,2,...2

Lower bound for real zeros
A number c is a lower bound for the set of real zeros of ƒ if ƒ(x) Z 0 whenever x < c

Reflection through the origin
x, y and (x,y) are reflections of each other through the origin.

Removable discontinuity at x = a
lim x:a ƒ(x) = limx:a+ ƒ(x) but either the common limit is not equal ƒ(a) to ƒ(a) or is not defined
