f: R R , then f(x)=x|x| will be

Options

  1. Amany-one-onto
  2. Bone-one-onto
  3. Cmany-one-into
  4. Done-one-into

Correct answer

B. one-one-onto

Step-by-step solution

Given, f: R R, f(x)=x|x| Redefined the function, f(x)= aligned -x², & x 0 aligned . The graph of f(x) shows that it is a bijective (one-one-onto) function.
