f(x) =e^x then f :R to R* one one, not onto and a,b €R f(a+b)=e^(a+b)=e^a.e^b=f(a).f(b) f is homomorphism so f is not isomophic
why do we consider f(x)=e^x ?
example consider kiya
sir function ko onto batane ka short tarika kiya hota hai?
x=f(y) mai convert karke domain find karo
sorry f Is not onto
yes I found the domain what next?
this domain is range of f if range of f = codomain then f is onto if range of f contain in codomain the f is not onto
kiska codomain? f(x) ka ya f(y) ka? please clarify
this domain of f(y) is range of f(x) if range of f(x) = codomain of f(x) then f(x) is onto if range of f(x) contain in codomain of f(x) the f(x) is not onto
sir codoamin of f(x) all real numbers hoga na?
yes
sir, hamesha codomain real number he hoga sare functions ke liye?
