Quadratic parent function (p. 546) The simplest

quadratic function f{x) = x2 or y = x2

Funcion cuadratica m adre (p. 546) La funcion cuadratica

mas simple f(x)=x2 o y = x2.

Example y = xz is the parent function for

the family of quadratic equations

of the form y = ax2 + bx + c.

Qualitative (p. 753)

qualitative.

Data that name qualities are Cualitativo (p. 753)

cualitativos.

Los datos que indican cualidades son

Example The data red, blue, red, green,

blue, and blue are qualitative data.

Quantitative (p. 753) Data that measure quantity and can

be described numerically are quantitative.

Cuantitativo (p. 753) Los datos que miden cantidades y

pueden ser descritos numericamente son cuantitativos.

Example The data 5 ft, 4 ft, 7 ft, 4 ft, 8 ft,

and 10 ft are quantitative.

Quantity (p. 4)

or counted.

Anything that can be measured Cantidad (p. 4)

contar.

Cualquier cosa que se puede medir o

Example A dozen is another way to describe

a quantity of 12 eggs.

Quartile (p. 746) A quartile is a value that separates a
finite data set into four equal parts. The second quartile (Q2)
is the median of the data set. The first and third quartiles
(Qi and Q3) are the medians of the lower half and upper
half of the data, respectively.

Cuartil (p. 746) Un cuartil es el valor que separa un

conjunto de datos finitos en cuatro partes iguales. El segundo

cuartil (Q2) es la mediana del conjunto de datos. El primer

cuartil y el tercer cuartil (Qt y Q3) son medianas de la mitad

inferior y de la mitad superior de los datos, respectivamente.

Example For the data set 2, 3, 4, 5, 5, 6 , 7,

7, the first quartile is 3.5, the

second quartile (or median) is 5,

and the third quartile is 6.5.

Radical (p. 16) An expression made up of a radical symbol
and a radicand.

Example Va

Radical (p. 16) Expresion compuesta por un sfmbolo radical

y un radicando.

Radical equation (p. 633) An equation that has a variable
in a radicand.

Example Vx - 2 = 12

Vx = 14

{Vx)2 = 142

x = 196

Radical expression (p. 619) Expression that contains
a radical.

Ecuacion radical (p. 633) Ecuacion que tiene una variable

en un radicando.

Expresion radical (p. 619) Expresiones que contienen

radicales.

Example V3, V5x, and Vx - 10 are

examples of radical expressions.
