Let f:R rarrR be definedas f(x) = x^4 Choose the correct answer |
|
Answer» f is one-one onto f(-1) = `(-1)^4` = 1 f(1) = f(-1) = 1 `therefore` f is not one-one The co-domain of f is R. the range of I is `[0, infty)`. Since range of f `NE` co-domain of f, f is not onto Hence f is neither one-one nor onto. |
