Question

f(x)=ex

Answer 1

ok....true?

Answer 2

?
What's the rest?

Answer 3

i win

Answer 4

rezale, that is a really hard question, because i cant even find the question mark

Answer 5

lmao

Answer 6

I should proof taht f(x)= ex

Answer 7

proof?

Answer 8

well you said it didnt you?

Answer 9

calculating the derivating using by difinition

Answer 10

You cant. f(x) just means function of x. There are infinity possibilities for f(x). sometimes it is e^x sometimes it isnt.

for f(x) = e^x.
The derivative is also e^x.

Answer 11

lol derivative of e^x dx

Answer 12

I mean e to the pwer x

Answer 13

what do you mean joshua? He said the right thing. Just it isnt a clear question

Answer 14

e^x dx the dx is only for integrals, not differentials

Answer 15

No, just write out derivative e^x. Dirty joke...

Answer 16

wait I think I'm mixing up derivatives and antiderivatives.

Answer 17

Yeah, sorry. Antiderivative e^x

Answer 18

I am not joking I should calculate it with difinition

Answer 19

What's the entire question?

Answer 20

nothing

Answer 21

So the question is only prove that f(x)=e^x?

Answer 22

yeah

Answer 23

Can't really help you there then, since f(x) simply means function of x. So you really only have the problem of e^x.

Answer 24

OoooooOoOo

Answer 25

Use http://en.wikipedia.org/wiki/Characterizations_of_the_exponential_function
the definition of e^x as a series
