Global Maximum - ANSWER Finds the highest y-number the function goes to
Global minimum - ANSWER Finds the lowest y-number the function goes to
Horizontal Asymptote - ANSWER a horizontal line that the curve approaches
but never reaches
inequality - ANSWER A mathematical sentence that shows the relationship
between quantities that are not equivalent
inflection point - ANSWER The point on a curve at which the curves concavity
changes; also called the point of inflection
Input-output pairs - ANSWER The representation of an input value and an
output value as an ordered pair, written (x,y)
, Interpolation - ANSWER A method of inserting new data points in the range of
a known set of data points
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
inverse function - ANSWER a function that "undoes" what the original function
does
least-squares regression method - ANSWER uses all of the data to separate a
mixed cost into its fixed and variable components
linear function - ANSWER A function whose graph is a straight line.
linear regression - ANSWER an algorithm to find a precise line of fit for a set
of data
Logistic function - ANSWER A function that produces an s-shaped curve and
contains two asymptotes
,Moore's Law - ANSWER the observation that computing power roughly
doubles every two years.
Multivariate - ANSWER involving more than two variables
order of operations - ANSWER the order in which operations in an expression
to be evaluated are carried out. 1. parentheses 2. exponets 3. multiplication and
divison 4. addition and subtraction (please excuse my dear aunt sally)
ordered pair - ANSWER A pair of numbers that give the location of a point on a
x and y grid. for example graph (3, 2)
Output Variables - ANSWER The output, represented by one or more letters,
such as m or d(t), produced by a function, based on the output variable
Polynomial - ANSWER a mathematical expression that is the sum of a number
of terms
Polynomial's degree - ANSWER The value of a polynomials largest exponent
Big Box Stores - ANSWER A very large store, typically over 50000 square
feet, of plain design, resembling a large box
Calculate the average rate of change - ANSWER The formula to compute an
average rate of change is
, quantitative variable - ANSWER a characteristic that can be measured
numerically
qualitative variable - ANSWER A variable that is not numeric; also called a
categorical variable, a qualitative variable describes data that fits into categories
A rental car company charges a flat fee of $39 for a car rental. They charge an
additional $0.62 for each mile driven.
Which function F represents the cost to rent a car, where m represents the number
of miles?
A. F(m)=39+0.62m
B. F(m)=39+0.62+m
C. F(m)=39m+0.62
D. F(m)=(39+0.62)m - ANSWER A

B. F(x)=200x-150
C. F(x)=200x+150
