Answer:

At x= 4 the given expression is undefined.

Step-by-step explanation:

In a given function , if the denominator becomes zero then the function is undefined.

Here, denominator is x-4 so at x = 4 it will become zero. So we can say that at x=4 , the function is undefined

Step-by-step explanation:

I am not fully sure what your teacher is aiming for. it friends very much on what you were just discussing in class (which I don't know).

but the first thing coming to mind is a minus sign ("-"). squaring a negative number removed the minus and makes the result equal to squaring the same positive number.

just for the undoing the 1/2 :

that is, because a fraction as exponent specifies in its denominator the root to be calculated for the basic value or expression.

so, 1/2 means square root. and yes, square is the inverse function of a square root, and it "undoes" the square root.

in exponent calculation it just means that for exponent 1 to the power of exponent 2 we simply multiply both exponents. and so, 1/2 × 2 = 1

FYI - the numerator still represents an original "to the power of" operation.

so, e.g. 3/2 would mean put the basis to the power of 3 and then do the square root of that result. or the other way around. these operations are commutative (the sequence does not matter).

Help !!!! rectangle pqrs has side lengths of 7 and 3 as shown on the grid below
Inessa05 [86]
Even though you have reflected this triangle, your side length would still be the same. Explanation: Reflection is when you take an object on your coordinate plain and put it somewhere else on the plain. So if side QR is 3 than side Q’R’ would also be 3. Hope this helps!

What is the geometric mean of 30 and 6
Alik [6]
Since we have 2 numbers, we'll be square rooting.

All we have to do to find the mean is multiply & square root the products.

30 × 6 = 180

\sqrt{180} = 13.42

You can use the same process and check my answer if you'd like; I rounded the square root, so you may get a different answer.
