" (c) "f:C rarr R,f(z)=|z|

Examine whether the following functions are one-one and onto : f : C rarrR,f(z)=|z| for all z in C , where C is the set of complex numbers.

Let f:R rarr R,f(x)=(x-a)/((x-b)(x-c)),b>c. If f is onto,then prove that a in(b,c)

Which of the following functions are injective and surjective? : f : Z rarr Z,f(x)=x^3

f : C to R : f (z) =|z| is

Let C be the set of complex numbers . Prove that the mapping f : C rarr R given by f(z) = |z| , AA z in C , is neither one - one nor onto .

Let C and R denote the set of all complex numbers and all real numbers respectively. Then show that f: C->R given by f(z)=|z| for all z in C is neither one-one nor onto.
