ОтветитьYe ye dekh ke bhi ho gyega ki x ki value +x rakhne par kitni naar sogn change hoga aur x ki value -x rakhne par kitni baar sing change hoga + mai koi sign change nhi hai tho no real solution aur - mai tho 1 baar hoga tho 1 real solution tho fer ek real solution hai iska
ОтветитьOption b)

ОтветитьIncreasing function does not always cut the real line !!
It cuts the real line if there are at least two points a, b say in R such that f(a)<0 and f(b)>0.
Be careful, don't make these important mistakes 🙏

ОтветитьThnaku so much sir mujhe is typeke question jaldi nhi samajh a rha tha lekin ab samajh gya..ki derivatives and power even h to inc. hoga

ОтветитьSir option B....... sir please bring more pyq series ❤❤❤❤
ОтветитьOption B
F(x) =++++
F(-x)=---+
In both case we see only one time sign change . So real solution is only one

ОтветитьCorrect Answer: (B)
As it is also an increasing function.
Purely galat: An increasing function does not necessarily cut the x-axis. Example e^x
ОтветитьOdd degree polynomial ka ek minimum real root rahe ga, aur f'(x)>0 that means it's never cuts x axis again. So one root .
ОтветитьOption b sir
ОтветитьSir please ek dedicated one shot bana sakte ho aap graphical transformations par because kaii questions graph se solve hojate h aur jo simple graph transformations h vo to easily draw hojati h but kai baar complex bhi aajate h thode unme dikkat aati h to please

ОтветитьB is correct option
ОтветитьDescartes se bhi same aara hai and zyaada easily aara hai
ОтветитьAnswer: Option(B)
Ninja hack: Whenever you'll see a function to only have odd powers then it'll only have only 1 real solution.
Thank you 👍
