Math Questions And Answers
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
function
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.
domain ( in a function)
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
range (in a function)
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)
ways to represent functions
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.
common denominator
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
least common multiple (LCM)
least common denominator (LCD)
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
ratio
ratio where quantity is compared to a hundred parts 1/2 = x/100 = 50%
percent
A ratio of two numbers measured in different units.
ex. $ 3.49 a gallon; 55 miles an hour
rate
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
proportion
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.
