Let f:N→N be a function defined as f(x)=9x2+6x-5. Show that f:N→S, where S is the range of f, is i invertible. Find the inverse of f and hence find f-1(43) and f-1(163).

Let f: $N \to N$ be a function defined as f(x)= $9 x^{2} + 6 x - 5$ . Show that f: $N \to S$ , where S is the range of f, is i invertible. Find the inverse of f and hence find $f^{- 1} (43) a n d f^{- 1} (163)$ .
