Find all critical numbers for the following function. Then use the​ second-derivative test on each critical number to determine

whether it leads to a local maximum or minimum.

Critical values are values where f'(x)=0 and the bounds of a function. Thus, let's solve for f'(x)!

f(x)=2x^3-3x^2+3x+8
f'(x)=6x^2-6x+3

Now let's set f'(x)=0

0=6x^2-6x+3
0=2x^2-2x+1

As it turns out, 2x^2-2x+1 isn't factorable!
This saves me some time because this means there are no critical numbers!

Given the points (2,k) and (0,−6), for which values of k would the distance between the points be 5–√ ?
natka813 [3]

The value of k are -5 and -7 if the distance between points (2,k) and (0,−6) is √5

<h3>What is a distance formula?</h3>

It is defined as the formula for finding the distance between two points. It has given the shortest path distance between two points.

The distance formula can be given as:

\rm d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

The question is:

Given the points (2,k) and (0,−6), for which values of k would the distance between the points be √5

\rm \sqrt{5}=\sqrt{(0-2)^2+(-6-k)^2}

5 = 4 + (6 + k)²

After solving:

\rm 4+\left(6+k\right)^2-4=5-4

(6 + k)² = 1

k = -5 or -7

Thus, the value of k are -5 and -7 if the distance between points (2,k) and (0,−6) is √5
