Question

Statement‐I:: If $f left parenthesis x right parenthesis$ is increasing function with concavity upwards, then concavity of $f to the power of negative 1 end exponent left parenthesis x right parenthesis$ is also upwards
Statement‐II:: If $f left parenthesis x right parenthesis$ is decreasing function with concavity upwards, then concavity of $f to the power of negative 1 end exponent left parenthesis x right parenthesis$ is also upwards.

Statement‐I is True, Statement‐II is True; Statement‐II is a correct explanation for Statement‐I
Statement‐I is True, Statement‐II is True; Statement‐II is NOT a correct explanation for Statement‐I
Statement‐I is True, Statement‐II is False
Statement‐I is False, Statement‐II is True

The correct answer is: Statement‐I is False, Statement‐II is True
