OpenStudy (amistre64):

when does a fraction = zero?

OpenStudy (anonymous):

never

OpenStudy (anonymous):

?

OpenStudy (amistre64):

.... try again

OpenStudy (amistre64):

if you have 0 out of 5 pieces, wouldnt that be 0/5 = 0?

OpenStudy (anonymous):

hmm im really bad at functions and graphs :'(

OpenStudy (anonymous):

yes^

OpenStudy (amistre64):

if you have 0 out of x pieces, then youd have zero still; 0/x = 0 right?

OpenStudy (anonymous):

yes

OpenStudy (amistre64):

can 1/x = 0/x ?

OpenStudy (anonymous):

no

OpenStudy (amistre64):

then the range of this function is not ALL real numbers is it? since its never equal to zero

OpenStudy (amistre64):

can we divide by a zero?

OpenStudy (anonymous):

u can but it will always be 0

OpenStudy (amistre64):

it will? 5/0 means that 0*n = 5 , what is the value of n?

OpenStudy (anonymous):

bothing times 0 equals 5?

OpenStudy (amistre64):

correct, so dividing by zero is UNDEFINED, not zero

OpenStudy (amistre64):

so the domain of our function doesnt include zero

OpenStudy (amistre64):

and the other key point is knowing something about direct and inverse variations; this ones inverse since x is on the bottom

OpenStudy (anonymous):

so then its only D?

OpenStudy (amistre64):

I covered all the needed information with you ... D is one of the right options, ther eis one more

OpenStudy (anonymous):

a and D?

OpenStudy (amistre64):

that would be best

OpenStudy (anonymous):

THANKS @amistre64

OpenStudy (anonymous):

:) REALLY APPRECIATEDD

OpenStudy (amistre64):

good luck ;)
