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.

State the domain of the numbers displayed in column x and column y. x y
ella [17]

We can not really tell in this question as you dont know the equation that is being used for the domain and range relationship but overall one should know that:

The set of values of the independent variable(s) for which a function or relation is defined as the domain of a function. Typically, this is the set of x-values that give rise to real y-values.

The range of a function is the complete set of all possible resulting values of the dependent variable (y, usually), after we have substituted the domain.

After a weekend at the beach, Lisa has $274 less than she had when she left. The equation that represents this situation is e=s−
Anon25 [30]
Well that's easy it basically tells you all you gotta do is plug in the numbers 

"E" is what you're trying to find out so you don't know that one it stays the same. 

"S" is the amount of money she started with and it says she started with $500 

And then she has $274 less than she started with. 

E = 500 - 274 

E= 226

She is left with $226 after her weekend at the beach. 

~Hope it helped~

Solve for x 2x^2 = 128<br><br> Answers <br> -6 and 6 <br> -8 and 8<br> -32 and 32 <br> -64 and 64
uysha [10]

Divide both sides by 2

x^2 = 128/2

Simplify 128/2 to 64

x^2 = 64

Take the square root of both sides;

x = √64

Since 8 * 8 = 64, the square root of 64 is 8

<em>x = -8 and 8</em>

<u>Answer: B -8 and 8</u>
