Answer: The correct option is B, i.e., "As x → ∞, f(x) → ∞, and as x → –∞, f(x) → ∞".
Explanation:
From the table it is noticed that the first row represents the value of x and the second row represents the value of f(x).
The value of f(x) is 14 at x = -5, after that the value of f(x) is decreased as the value of x increases.
The value of f(x) remains unchanged when the value of x approaches to 0 from 1.
The value of f(x) is -6 at x = 0, after that the value of f(x) is increased as the value of x increases.
From the table it is noticed that as the value of x approaches to positive infinity the value of f(x) is also approaches to positive infinity.
From the table it is noticed that as the value of x approaches negative infinity the value of f(x) is also approaches to positive infinity.
These statement are shown in second option, therefore the second option is correct.
Answer:
2
Step-by-step explanation:
1+1=2
-- All of the non-zero digits are: 1, 2, 3, 4, 5, 6, 7, 8, and 9 .
that's nine digits all together.
-- The odd ones are 1, 3, 5, 7, and 9 .
There are five odd ones.
-- The even ones are 2, 4, 6, and 8.
There are four of them.
-- Two odd digits are already used, and we can't repeat them.
So we have 7 choices left for the last digit ... 3 odds and 4 evens.
-- Probability = (number of successful choices) / (total possibilities)
Successful choices . . . an odd digit, 3 available
Total possibilities . . . 7 unused digits
Probability = 3/7 (choice C)
Answer:
Step-by-step explanation:
11. 1:7 =10:70
7/21 = 5/15
12. 2:11 =6:33
33/66 = 4/8
13. 3:5 =60:100
5/10 = 15/30
