C957 APPLIED ALGEBRA EXAM
REPORTED QUESTIONS WITH
ANSWERS
information age - Answer-The present time, when information is widely available to
many people through computer technology.
input - Answer-A quantitative variable that is chosen to find a solution, or output, of a
function.
input-output pairs - Answer-The representation of an input value and an output value as
an ordered pair, written (x, y).
instantaneous rate of change - Answer-The rate of change at a particular moment, as
opposed to average rate of change, which is change over a period of time.
interpolation - Answer-A method of inserting new data points in the range of a known
set of data points. ("Inter" means among.)
interrelated causality - Answer-An output produced by the interaction of several
connected, or related, inputs.
interval - Answer-A range of numbers that include all the real numbers between its
endpoints.
inverse - Answer-Opposite in position, direction, order, or effect.
inverse function - Answer-A function that undoes, or reverses, the action of the another
function.
least-squares regression (lsr) algorithm - Answer-The most commonly used regression
algorithm (process), which is generally seen as the best technique for regressions.
limiting factors - Answer-A circumstance that tends to prevent an activity or quantity
from expanding or changing.
line graph - Answer-A graph that displays data points connected by segments of straight
lines.
line of best fit - Answer-A straight line on a graph showing the best possible match for
the data; also called a "trend line."
, linear functions - Answer-A function that produces a straight line (linear means
"straight"), indicating a constant increase or decrease.
linear regression - Answer-A regression that finds the best-fit line based on at least two
data points.
local maximum - Answer-The maximum for a particular interval, or range of a function.
local minimum - Answer-The minimum for a particular interval, or range of a function.
logistic functions - Answer-A function that produces an s-shaped curve and contains two
asymptotes.
maxima - Answer-The greatest amount, or highest value, on a function's graph.
maximum value - Answer-The largest value in a set of data.
minima - Answer-The smallest amount, or lowest value, on a function's graph.
minimum value - Answer-The smallest value in a set of data.
moore's law - Answer-The observation by Gordon Moore in 1965 that the number of
transistors on a silicon chip doubles periodically, which means that computing power
also doubles; this is not a "law" in the conventional sense, rather more like a theory.
multivariate - Answer-Involving a number of different - though not necessarily
independent - variables.
order of operations - Answer-The conventional rules for solving math expressions: 1)
Parentheses and brackets from the inside out; 2) Exponents; 3) Multiplication and
division from left to right; 4) Addition and subtraction from left to right.
ordered pair - Answer-A pair of numbers used to locate a point on a graph, written in the
form (x, y) where x is the x-coordinate and y is the y-coordinate.
origin - Answer-On a graph, the starting point where both x and y are equal to zero, and
the x-axis and the y-axis intersect.
outlier - Answer-A data point that "lies" significantly "outside" the trend in a set of data.
output - Answer-A quantitative variable that is produced by a function when an input is
chosen.
output variable - Answer-The output, represented by one or more letters, such as m or
d(t), produced by a function, based on the input variable.
