Determine all critical points for the following function. f (x )equals 2 x (4 minus x )cubedf(x)=2x(4−x)3 xequals=nothing (Use a comma to separate answers as needed.)

The critical points of the function

f(x) = 2x(4 - x)³

are x = (1, 4)

Step-by-step explanation:

Given the function

f(x) = 2x(4 - x)³

To find the critical points, we differentiate f(x) to obtain f'(x), and then find the zeros of the resulting quadratic function.

Now, differentiate f(x).

f'(x) = 2(4 - x)³ + 2x(-1)×3(4 - x)²

= 2(4 - x)³ - 6x(4 - x)²

= 2(4 - x)²(4 - x- 3x)

= 2(4 - x)²(4 - 4x)

f'(x) = 8(4 - x)²(1 - x)

Now we set f'(x) = 0 and solve

8(4 - x)²(1 - x) = 0

=> 8(1 - x) = 0

=> 1 - x = 0

=> x = 1

Or

(4 - x)² = 0

x = 4 twice.

So x = (1, 4)

Therefore, the critical points are x = (1, 4)

step-by-step explanation:

10.50 + taxes which added up to 11.50

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

⇒ option b is correct.
