Answer:

\large\boxed{Domain:\ x\in\mathbb{R}\to\text{the set of all real numbers}}

Step-by-step explanation:

The domain of roots:

\sqrt[n]{p(x)}

If n is an odd number, then p(x) can be any real number.

If n is an even number, then p(x) must be a non-negative number.

We have

f(x)=\sqrt[3]{2x^2-3x-9}

n = 3 → odd number.

Therefore the domain is the set of all real numbers.

the combination formula is as follows.
nCr= \frac{n!}{r!(n-r)!}
plug in 4 for n and 2 for r.

Could someone explain why (-4)² is equal to 16 but -4² is equal to -16​
erica [24]

Answer:

It's all about the brackets.

Step-by-step explanation:

If we do (-4)^2, the brackets make it -4 x -4 and the two negatives make a positive of 16.

If we do -4^2, that means that the 4 is squared before putting the minus sign there so you have 4x4 = 16 then put the minus to get -16.

Hope this helps!
