rational functions Flashcards
1
Q
what is a rational function’s form?
A
f(x) = n(x) - polynomial functions
——
d(x) - polynomial functions
2
Q
vertical asymptotes
A
when a x- value would give zero in the denominator
3
Q
horizontal asymptotes
A
tell us what the curve does as x –> +/- infinity
4
Q
horizontal asymptotes- if the degrees are equal
A
the horizontal asymptote is the ratio of the leading terms
5
Q
horizontal asymptotes- degree greater in denominator
A
the horizontal asymptote is 0
6
Q
horizontal asymptote- degree greater in numerator
A
the curve shoots up or down to +/- infinity
7
Q
holes
A
occurs where there is a common factor in the numerator and denominator
