Identify the domain of a radical function with an odd index: A) 0 < x < ∞ B) 0 ≤ x < ∞ C) –∞ < x ≤ 0 D) –∞ < x < ∞

(D)

Step-by-step explanation:

These two basic rules apply when determining the domain of radical functions.

For simplicity, the domain of the radical function is the number under the root symbol.

Take for example, the number 2 is even and 3 is odd.

Thus, for even index, the domain must be greater than or equal to zero.

However:

Thus, for an odd index, the domain can be any real number from .

The correct option therefore is D.

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)

step-by-step explanation:

is their an equation anywhere i can take a   look at it and see if i am right.
