Find the inflection point of the function of f(x) = x³ -6x² +12x

Mathematics
1 answer:
Wewaii [24]3 years ago
5 0

Points of inflections are zeroes of the second derivative. We have:

f(x)=x^3-6x^2+12x\implies f'(x)=3x^2-12x\implies f''(x)=6x-12

So, the second derivative equals zero if and only if

f''(x)=0\iff 6x-12=0 \iff 6x=12 \iff x=2

So, this is the only point of inflection of this function.

julsineya [31]

Answer: Cola is more profitable over Coffee

Step-by-step explanation:

E(cola) = 0.3 * 1500 + 0.7 * 5000

E(cola) = 450 + 3500

E(cola) = 3950

E(coffee) = 0.3 * 4000 + 0.7 * 1000

E(coffee) = 1200 + 700

E(coffee) = 1900

From the decision tree which is attached, and the calculations above, it would be advised that the firm should focus on Cola, since it has a higher expected revenue of $3950, compared to the expected revenue of $1900 for coffee.
