Let `f: NrarrR`, be a function defined as `f (x) = 4x^2 + 12x + 15, forall x in N`, show that `f: NrarrS` where S, is range of f is invertible.

Let f: Nrar R be a function defined as : f(x) = 4x^2 + 12 x + 15 . Show that f: N rarr S where S is Range f is invertible. Find the invere of 'f'.

Let f : N rarr N be a function deifned by f(x) = 9x^2 + 6x - 5 . Show that f : N rarr S , where S is the range of 'f', is invertible. Find the inverse of 'f' and hence, find f^-1(43) and f^-1(163)
