Question

The set of value (s) of $a$ ’for which the function $f left parenthesis x right parenthesis equals fraction numerator a x to the power of 3 end exponent over denominator 3 end fraction plus left parenthesis a plus 2 right parenthesis x to the power of 2 end exponent plus left parenthesis a minus 1 right parenthesis x plus 2$ possess anegative point of inflection‐

$(- \infty, - 2) \cup (0, \infty)$
{-4/5}
(-2,0)
empty set

The correct answer is: $left parenthesis negative infinity comma negative 2 right parenthesis union left parenthesis 0 comma infinity right parenthesis$
