Question

Which of the following functions will produce the graph shown below?

Answer 1

first
be careful about x=1
it is not continues (so is denominator root ) but have limit around x=1 so (it is nominator's root also)
check this !
only one of them has condition

Answer 2

implicit
x=-3 is vertical asymptote
only one of them has this asymptote

Answer 3

3rd method
x=-1 is a root for function

Answer 4

so then it's a?

Answer 5

not a because
in choice a f(-1) is not zero
try again

Answer 6

would it be d?

Answer 7

not d
f(-1) is not zero too

Answer 8

try again

Answer 9

c

Answer 10

not c
look the figure
the root of function is in x=-1
so f(-1) must be zero
it is only b

Answer 11

did you get ?

Answer 12

why is it -1?

Answer 13

oh wait i see. yeah i get it
