wat hav u done in da 3rd quadrant????

y=x for x ξ (-∞,0)

it is log_e naa?

because for x<0
0<e^x<1

so {e^x}=e^x

so log{e^x}=log(e^x)=x...

huh!!

OH K!!!
I GOT UR MISTAKE AB.....

TELL ME WAT IS {-.7}

THE CORRECT ANS = .3 AND NOT .7!!!!!!!!!

REMEMBER.... I M SURE ABT THIS....

PROOF : BY DEFINITION {X} = X-[X]

NOW U'LL GET IT.....

NISHANT SIR!!!!

AM I WRONG????

3RD QUADRANT OF ABHI'S SOLN I FEEL IS WRONG!!!!

NO NO NO SORRY!!!!!!!!!!!!!!!1

I WAS CONSIDERING FRACTNAL PART IN X....

MY MISTAKE......

YA e^x is always positive so no issues!!!!!!!

y does it get denser and steeper as we move right

@amritansh

as we know an exponential function increases very quicky with ever increasing slope....and it takes up integral and fractional values at a very quick pace
so for x>0 its fractional part changes rapidly..hence its log
