the denominator cannot be zero, because the division by zero is not defined, therefore:
![\begin{gathered} x^2-9=0 \\ \text{Solving for x:} \\ x^2=9 \\ \sqrt[]{x^2}=\sqrt[]{9} \\ x=\pm3 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20x%5E2-9%3D0%20%5C%5C%20%5Ctext%7BSolving%20for%20x%3A%7D%20%5C%5C%20x%5E2%3D9%20%5C%5C%20%5Csqrt%5B%5D%7Bx%5E2%7D%3D%5Csqrt%5B%5D%7B9%7D%20%5C%5C%20x%3D%5Cpm3%20%5Cend%7Bgathered%7D)
Therefore the domain of (f o g)(x) is:
Answer:
Step-by-step explanation:
Answer:
The answer is 256
.
Step-by-step explanation:
To solve for the volume of the sphere, start by using the sphere volume formula, which is V =
. However, in this formula, 3 will be used instead of (
).
Next, plug in the information given from the problem, and the formula will look like V =
(3) (
).
Then, solve the equation, and the answer will be 256
.
Answer:
the answer is A {-5,-3,-1}
