Let f : R R defined by f ( x )=5 x ^4+2 . Then

Options

  1. Af is one-one but not onto
  2. Bf is onto but not one-one
  3. Cf is both one-one and onto
  4. Df is neither one-one nor onto

Correct answer

D. f is neither one-one nor onto

Step-by-step solution

We have a function f : R R at f(x)=5 x^4+2 Sin f(-2)=f(+2) function is not one-one and f ( x ) 2 function is not on to. hence function is neither one-one nor onto.
