ganeshie8 (ganeshie8):

why ?

OpenStudy (anonymous):

i read it wrong, i think its: all of these are true

ganeshie8 (ganeshie8):

explain why

OpenStudy (anonymous):

its false that "all of these are true" because i dont think the graph of f has an inflection point at x=0

ganeshie8 (ganeshie8):

haha, you're right but your teacher wants you pick second option

OpenStudy (anonymous):

oh

ganeshie8 (ganeshie8):

since f'(x) is increasing, we have f''(x) > 0 so there cannot be any inflection points.

kk :) thank u!!!!!!!

ganeshie8 (ganeshie8):

as you said, logically `option b` and `option d` are false but ur dumb teacher wants you pick option b lol it is a good observation from you :) tell it to your teacher, he will be impressed :P

ganeshie8 (ganeshie8):

`option a` and `option c` are not false statements

OpenStudy (anonymous):

thanks :)

ganeshie8 (ganeshie8):

dont forget to inform your teacher :)
