Question

$text If end text f left parenthesis x right parenthesis equals a x to the power of 7 plus b x cubed plus c x minus 5 text and end text f left parenthesis negative 7 right parenthesis equals 7$ , then the range of $f left parenthesis 7 right parenthesis plus 17 cos x text is end text$

$[- 3 / 4, 0]$
$[0, 3 / 4]$
$[- 34, 34]$
${- 34, 34}$

The correct answer is: $left square bracket negative 3 divided by 4 comma 0 right square bracket$

$f left parenthesis x right parenthesis plus f left parenthesis negative x right parenthesis equals negative 10 not stretchy rightwards double arrow f left parenthesis 7 right parenthesis plus f left parenthesis negative 7 right parenthesis equals negative 10 not stretchy rightwards double arrow f left parenthesis 7 right parenthesis plus 7 equals negative 10 not stretchy rightwards double arrow f left parenthesis 7 right parenthesis equals negative 17 f left parenthesis 7 right parenthesis plus 17 cos x equals negative 17 plus 17 cos x text Range end text equals left square bracket negative 3 divided by 4 comma 0 right square bracket$
