Sir u r the best teacher god bless you...☺️.

[Shru]

Q.7) ii) f : R->R
f(x)=1+x^2
Ans... f(1)=1+(1)^2=1
f(-1)=1+(-1)^2=1
So, 1 is not = -1 -> f(1)=f(-1)
So f is not one-one.

For x belongs to R
f(x)=1+x^2 belongs to R+
Range of f, Rf = R+ is not =R is not equal to codomain.
So f is not onto function.


Hope it will help you.

Sir in Qno 7(i)
In one one if we put 1/4 & 0 then result is 3...So, in this way it will be many one...

Sir agar √2 domain mai dal kar dekh toh 3-4√2 aa raha hai toh √2 ka image unique aur real number hoga jise ye one one function ho

[prix]

Sir you are best teacher, , God blesses us

[Mandeep_]

Sir iske 2nd part ka NCERT justification to do pls !!

[maxislive]

Sir if we put x=1/4 in f(x)=3-4x . Then we get 3 but 3 is range of 0 . Then how is possible. 2:15

[sunitatiwari]

Sir, agar bijective nhi h to justify nhi krna hota kya??

[Shivam_pandit]

Sir (ii) vale me justify ni karna hai kya...??

[rajnisoni]

Sir yeh kese pta chlega kha pe f(x) =f(y) .x =y krna hai or kha pe domain unique Hai toh functions one one Hai yeh likhna Hai?
