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

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

Let f:N rarr R be a function defined as f(x)=4x^(2)+12x+15. show that f:N rarr S, where S is the range of f, is invertible.Also find the inverse of f

Let f:N rarr R be a function defined as f(x)=4x^(2)+12x+15 . Show that f:N rarr S , where S is the range of f, is invertible. Also find the inverse of f. Hence find f^(-1)(31) .
