3RDQ MASTERY TEST 2 Flashcards
a function m is a composite of functions f and g if m(x)=f[g(x)]
composite function
the domain of m is the set of all numbers x such that x is in the domain of g, and g(x), is in the domain of f
composite function
quotients of polynomial functions
rational functions
in rational functions, what is q(x) in
p(x)/q(x)
q(x) is not equal to 0
domain of rational functions
all real numbers except x-values that will make the denominator zero
conditions of rational functions
bawal fraction as an exponent
bawal square root
no negative exponent
what are the things you need to determine in graphing rational functions
vertical asymptote, relationship of the degree of the numerator and denominator (another aymptote), critical points in the table of values
what are the asymptotes when n
