Math Placement Exam Questions With
Revised Answers
Graph ≥, ≤ - answer✔✔solid line
graph >, < - answer✔✔DOTTED line
every, each, per (writing equations) - answer✔✔rate/ set y value equal to (multiply this value by
the x variable)
When writing an equation or working ANY inequality problem what does it help to do first? -
answer✔✔write out what's happening
What should you double check for EVERY time - answer✔✔writing problem down wrong
(NEGATIVE SIGNS), uncarried negative signs, unflipped inequality signs, undotted lines,
incorrect multiplication, fully simplified
distance = - answer✔✔rate x time
When solving a system of equations can you add the equations together if one of the variables
will cancel out? - answer✔✔YES
What should you always write out when doing your work? - answer✔✔Fraction conversions,
simplification steps, line graphs (interval notation)
What standard does an equation/ graph have to meet to be considered a function? -
answer✔✔Each input can only have one output
How do you translate a graph up or down? - answer✔✔The value outside of the parentheses
(DONT change sign)
How do you translate a graph side to side? - answer✔✔The value inside the parentheses
(CHANGE SIGN)
Translate -(x + 3)^3 - 2 from -x^3 - answer✔✔left 3, down 2
When translating do you need to solve the equation? - answer✔✔No, just look at the numbers
inside (side to side change sign) and outside (up and down DONT change sign) the parentheses
U represents - answer✔✔Numbers in EITHER set (Union)
⋂ represents - answer✔✔Numbers in BOTH sets (Intersection)

What should you always physically mark on inequality graphs that are getting compared before
attempting to solve the problem? - answer✔✔Where the graphs intersect
BETC - answer✔✔divide the top leading coefficient by the bottom leading coefficient (Bottom
Equals Top Coefficient HORIZONTAL ASYMPTOTE)
BOTU - answer✔✔there is no horizontal asymptote, find slant asymptote (Bigger On Top
Undefined)
How do you find the slant asymptote? - answer✔✔Divide the ENTIRE numerator by the
ENTIRE denominator, the slant asymptote is the quotient, ignore the remainder (might include
division with variables raised to exponents)
How do you find the vertical asymptote? - answer✔✔Set the denominator equal to 0
sin - answer✔✔csc
cos - answer✔✔sec
