Let the function f : R rarr R be defined by f(x) = cos x , AA x in R . Show that f is nether one - one nor onto .

Let the function f:R→R be defined by f(x)=cosx,∀x∈R. Show that f is neither one-one nor onto

let the function : f R rarr R to be defined by f(x) = cos x for all x in R is neither one-one nor onto.

Show that the function f : R rarr R defined by : f(x) = x/(x^2+1) AA x in R , is neither one-one nor onto.

A function f : R to R is defined by f(x) =x^(2) .Then show that f is neither nor surfection .

Let the function f:R rarr R be defined by f(x)=2x+sin x for x in R .Then f is (a)one-to-one and onto (b)one-to-one but not onto (c)onto but not-one-to-one (d)neither one- to-one nor onto

Show that the function f:R rarr R defined by f(x)=(x)/(x^(2)+1)AA x in R is neither one-one nor onto.Also if g:R rarr R is defined by g(x)=2x-1 find fog(x)
