Find the Domain of each rational
function:
3.3
3.3
#13 (see back of book)
#14 (all real numbers, except x = 3 or x = 4)
#15 (see back of book)
#17 (see back of book)
#18 (all real numbers, except x =
1) (to do this, set x4-1 = 0, and
then solve for x)
#20 (all real numbers)
Describe a function, from a graph:
#23 (see back of book)
#25 (see back of book)
#27 (see back of book)
Find the asymptotes
(vertical, horizontal/oblique)
Find the asymptotes
(vertical, horizontal/oblique)
#41 (see back of book)
#42 (vertical: @ x = 6 ;
horizontal: @ y = 3)
#43 (see back of book) (hint: is this
#46 (vertical: @ x = 1 ;
no horizontal or oblique
asymptotes, but the function will
have end behavior like 4x2)
#48 (vertical: @ x = 0, x = -2 ;
horizontal: @ y = 0)
#51 (see back of book)
rational function in lowest terms?)
#45 (see back of book)
