Answer:
Critical or Key numbers
the intervals which satisfy the inequality
b) fraction on the right-hand side.
Critical
that the denominator can not be equal to zero
Step-by-step explanation:
When solving a polynomial inequality by hand, the solutions of the associated equation are called the Critical or Key numbers. These numbers divide up the number line into regions that contain or do not contain the intervals which satisfy the inequality.
b. When solving a rational inequality by hand, the solutions of the associated equation as well as values that make the fraction on the right-hand side of the rational expression zero are called the Critical numbers. The restriction of a rational expression is that the denominator can not be equal to zero included (Undefined)included in the solution set.
As you know, the domain is the values "x" can safely take on.
well, for a logarithmic expression, it can never have an expression of 0, namely in this case, x + 4 must never be 0, since such a logarithm doesn't exist.
now, x + 4 = 0 ---> x = -4.
thus if "x" ever becomes -4, we'd end up with log₃(-4+4), or log₃(0), which is a no dice.
so the domain is all values except -4.

Answer is Choice B. 1:1</h3>
Explanation:
We have three numbers that aren't even, and they are {1,3,5}
There are three numbers that are even, and they are {2,4,6}
The odds in favor of not getting an even number is 3:3 = 1:1
To list the odds in favor, you write the number of ways to get what you want, followed by a colon, then the number of ways to get what you don't want. In this case, both counts are 3. The ratio 3:3 reduces to 1:1 after dividing both parts by 3.
