The domain of a function is all of the values of x for which the function is defined. If we substitute 4, the answer is 0. However, when any number smaller than +4 is substituted, the equation becomes:
y = sqrt(negative number) which is undefined. Thus, the domain is
D: x ≥ 4
The range of the function can be determined by the domain. The lowest number the equation will yield is negative infinity because when we take the square root of a positive number, there is one positive root and one negative root. For example, sprt(4) = +2 and -2
Thus, the range is
R: -∞ < y < ∞
Answer: 1=2x 2=(0, 1/4)
Step-by-step explanation:
<h3>Given:</h3>
<h3>To find:</h3>
- The approximate volume of the given sphere.
<h3>
Solution:</h3>

Let's substitute the values according to the formula.
Let's solve!


Now, well have to round off to the nearest hundredth.

<u>Hence,</u><u> </u><u>the</u><u> </u><u>volume</u><u> </u><u>of</u><u> </u><u>the</u><u> </u><u>given</u><u> </u><u>sphere</u><u> </u><u>is</u><u> </u><u>523.6</u><u> </u><u>cubic</u><u> </u><u>units</u><u>.</u>
Note: If your using π as π you'll get this answer.
