    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

    eduncle-logo-app

    why do we consider f(x)=e^x ?

    eduncle-logo-app

    example consider kiya

    sir function ko onto batane ka short tarika kiya hota hai?

    eduncle-logo-app

    x=f(y) mai convert karke domain find karo

    eduncle-logo-app

    sorry f Is not onto

    eduncle-logo-app

    yes I found the domain what next?

    eduncle-logo-app

    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

    eduncle-logo-app

    kiska codomain? f(x) ka ya f(y) ka? please clarify

    eduncle-logo-app

    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

    eduncle-logo-app

    sir codoamin of f(x) all real numbers hoga na?

    eduncle-logo-app

    yes

    eduncle-logo-app

    sir, hamesha codomain real number he hoga sare functions ke liye?
