For the function illustrated above, what is the domain? A{1, 2, 3, 4, 9, 12} B{1, 4, 9, 12} C{2, 3, 4} D{4, 9}
marshall27 [118]
Answer:
The correct option is C
C) (2,3,4)
Step-by-step explanation:
Domain can be defined as the set of all possible values of input, for which we can calculate the values of output. The values of input are independent, while the values of output are dependent on the values of input.
In the diagram, we can see that the arrow represents that for a certain number in A, we get a number from B. Which means that A represents the input while B represents the output.
As A is the input, all values of A form the domain of the function, which means that domain in {2,3,4}
Answer: - 9/8
Step-by-step explanation:
correct answer is option d.
<u>Step-by-step explanation:</u>
Here, we have The following expression to check Which of the following is a polynomial with roots: −square root of 3 , square root of 3, and 2 :
<u>a. x3 + 3x2 − 5x − 15
</u>
For 
, 
⇒ 
. So, this isn't the one. We move on further!
<u>b. x3 + 2x2 − 3x − 6
</u>
For , 
⇒ 
= 0 .
For 
, ⇒ 
= 0.
For 2 , ⇒ 
. So, this isn't the one. We move on further!
<u>c. x3 − 3x2 − 5x + 15
</u>
For , 
⇒ 
. So, this isn't the one. We move on further!
<u>d. x3 − 2x2 − 3x + 6</u>
For , 
⇒ 
= 0 .
For , ⇒ 
= 0.
For 2 , ⇒ 
= 0.
Therefore, correct answer is option d.
