An equation of the line tangent to y=x3+3x2+2 at its point of inflection is A. y=−6x−6y is equal to negative 6 x minus 6

B. y=−3x+1y is equal to negative 3 x plus 1

C. y=2x+10y is equal to 2 x plus 10

D. y=3x−1

Explanation:

Given

Required

Determine the equation at the point of inflection

The point of inflection of a curve is the point where the second derivative is 0.

So:

First derivative is:

Second derivative:

Equate to 0

Solve for x

Next, we calculate the slope (m) of the point using the first derivative.

Substitute -1 for x in

To get the y equivalent;

Substitute in

Lastly, we calculate the line equation using:

Where

and

So, we have:

Make y the subject

Hence, the equation is:

wow this is going to be a long one

cats shouldn't be kept inside their whole life they should be out in nature in the fresh air but because of our technology advances it has become unsafe for our furry friend to be outside in the city's, because they could be hit by vehicles. in city's yes i agree being inside isn't the worse thing, but if you live somewhere rural you should let your cats outside, yes some animals hunt cats but i don't think cats should be kept inside confined to such a small space.

btw this is my opinion
