Hi there!

Let $x$ represent "the number".

A number added by 7 is the same as that number times four minus eleven.

A number added by 7 ⇒ $x+7$

Is the same as ⇒ $x+7=$

The number times four ⇒ $x+7=4x$

Minus eleven ⇒ $x+7=4x-11$

Find the value(s) of x such that f''(x)=0

Goryan [66]

$f(x)=\dfrac x{x^2+2}\implies f'(x)=\dfrac{2-x^2}{(x^2+2)^2}\implies f''(x)=\dfrac{2x^3-12x}{(x^2+2)^3}$

The denominator is always positive, so any $x$ for which $f''(x)=0$ is determined only by the numerator:

$2x^3-12x=0\implies f''(x)=0$
$2x^3-12x=2x(x^2-6)=2x(x-\sqrt6)(x+\sqrt6)=0\implies x=0,\pm\sqrt6$
