Let `f : N to X : f(x) =4x^(2) +12x +15 . " Then " f^(-1)(y)=?`

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

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

Let f: N to Y : f(x)=x^(2) " where " Y = " range " ( f) . Show that f is invertible and find f^(-1)

Let f:N->N be defined by f(x)=x^2+x+1,x in N . Then f(x) is

Let f:N->N be defined by f(x)=x^2+x+1,x in N . Then f(x) is

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 f : N rarr N be a function defined as f(x) = 4x^(2) + 12x + 15 is invertible (where S is range of f). Find the inverse of f and hence find f^(-1)(31) .
