Questions and CORRECT Answers
function - CORRECT ANSWER A relationship from one set (called the domain) to another
set (called the range) that assigns to each element of the domain exactly one element of the range
domain ( in a function) - CORRECT ANSWER the first number/element in a set of ordered
pairs, in (2,5) 2 is a member of the domain; in (x,y) x is a member of the domain
In a set of ordered pairs each member of the domain must have only one partner in the range to
be a function.
range (in a function) - CORRECT ANSWER the second number/element in a set of ordered
pairs, in (2,5) 5 is a member of the range; in (x,y) y is a member of the range
ways to represent functions - CORRECT ANSWER as a set of ordered pairs
on a T chart (2 column table)
by having two sets (domain and range) and drawing a line connecting each member of the
domain with a member of the range
by a number equation ex. f(x) = x+2 = y
by charting the set of ordered pairs on a grid (uses the x and y axis to chart)
common denominator - CORRECT ANSWER 1/4 & 3/4 have a common denominator (4).
A denominator that is the same in two or more fractions; two or more fractions having the same
denominator.
, least common multiple (LCM)
least common denominator (LCD) - CORRECT ANSWER LCM is the smallest number that
two or more numbers can be divided into; least common multiple of the denominators of two or
more fractions is needed to add fractions.
Multiples of 3: 3,6,9,12,15
Multiples of 5: 5,10,15,20,25
15 is least common multiple (LCM) and therefore the least common denominator (LCD) of 1/3
and 1/5 is 15 so you convert:
1/3 = 5/15
1/5 = 3/15
ratio - CORRECT ANSWER the quotient of two numbers or quantities showing the relative
sizes two numbers or quantities 3/4 or 3:4
3:4 could be used to express 3 girls for every 4 boys
percent - CORRECT ANSWER ratio where quantity is compared to a hundred parts 1/2 =
x/100 = 50%
rate - CORRECT ANSWER A ratio of two numbers measured in different units.
ex. $ 3.49 a gallon; 55 miles an hour
proportion - CORRECT ANSWER The relationship of one thing to another in size, amount,
etc. Size or weight relationships among structures or among elements in a single structure. An
equation stating that two ratios are equal.
ex. a/b = c/d can also be written a:b c:d
translation - CORRECT ANSWER A shift of a graph horizontally, vertically, or both, which
results in a graph of the same shape and size, but in a different position.
When you slide a figure along a line.
