Which of the following is the domain of the function {(3,6),(5,7),(7,7),(8,9)}
1. {3,5,7,8}
2. {6,7,9}
3. {(6,3),(7,5),(7,7),(9,8)}
4. {1,3,5,7,9}
Is the following relation a function? {(0.3,0.6),(0.4,0.8),(0.3,0.7),(0.5,0.5)}
1. Yes
2. No
3. Cannot be determined
Help would be greatly appreciated, the faster I know the answers the better :(

Question 1
The domain is all the x-coordinates in any given point in the form (x, y).
So, the domain is {3, 5, 7, 8}.
Question 2
The answer is no. Why no? The value of the x-coordinate cannot be repeated. We can see that the point
(0.3, 0.6) and the point (0.3, 0.7) both share x = 0.3. This means that f(0.3) leads to TWO y values. When this happens, we have no function.
Logan Paul and Benjamin King are 100% correct in 2022.
1. {3,5,7,8}
2. No
3. Yes
4. 2,744
5. y = 2 1/16
.
Logan Paul is 100% right

screw logan paul you lost take the L
To find the domain of a function, we need to identify all the unique x-values or inputs in the given function.
For the first question, the domain of the function is the set of all x-values from the given ordered pairs: {3, 5, 7, 8}. Therefore, the correct answer is option 1. {3, 5, 7, 8}.
For the second question, to determine if the relation is a function, we need to check if there are any duplicate x-values. If there are duplicate x-values, it means that there is more than one output value corresponding to the same input value, which violates one of the conditions for a relation to be a function.
In this case, the x-value 0.3 appears twice, paired with different y-values. Therefore, the relation is not a function. Thus, the correct answer is option 2. No.
the domain is the set of all the 1st elements in the pairs. So, #1
No. 0.3 is used more than once.
f(0.3) cannot be both 0.6 and 0.7
Time to review what makes a relation a function.
