Find the inflection point of the function of f(x) = x³ -6x² +12x
Wewaii [24]

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.

4n - 2n = 4<br><br>what's the answer for this ?
Mademuasel [1]
Hey there!
First, we will do the subtraction with the two like terms on the left. I know they're like terms because although they have different coefficients, they have the same variable.
We have:
2n=4
Divide both sides by 3 to get:
n = 2
Hope this helps!

In this problem, how would I find the value of Z ?
BabaBlast [244]

Answer:

z = 30

Step-by-step explanation:

WX and VU are congruent

2z + 10 = z + 45

subtract z from both sides (z + 10 = 45)

subtract 10 from both sides (z = 30)

the answer is z = 30
