Show that the function f : R rarr R defined as f(x) = x^(2) is neither one-one nor onto.

Show that the function f: R toR. defined as f (x) =x ^(2), is neither one-one nor onto.

Show that the function f: R toR. defined as f (x) =x ^(2), is neither one-one nor onto.

Show that the function f: R toR. defined as f (x) =x ^(2), is neither one-one nor onto.

Show that the function f:R rarr R defined as f(x)=x^(2) is neither one-one nor onto.

Show that the function f: R to R defined by f(x)=2x^(2) , is neither one - one onto.
