G `( x ) =

2 + k x = 0
k x = -2
k = -2: x = - 2 : 2/3 = - 2 * 3/2
k = - 3Answer:
for k= - 3, the function g ( x ) have a critical point at x = 2/3.
3.97, 4 is less than 5 so you round down, and you should round to the nearest hundredths
The correct answer is:
[D]: "

" .

;
Simplify the "denominator" ; → (b + 2b = 1b + 2b = 3b) ;
and rewrite:

;
Cancel out the "b" in the "numerator" to a "1" ;
and cancel the "3b" in the "denominator to a "3" ;
{since: "b ÷ b = 1 "; and since: "3b ÷ b = 3" } ;
and rewrite as:
