Answer: All real numbers except 3
Out of four statements, only (c) is correct
Step-by-step explanation:
Given: The mean score for a math test taken by Class A is 84, with the scores ranging from 78 to 94. The mean score for the same math test taken by Class B is 76, with the scores ranging from 68 to 88
a) Incorrect: The highest score was in Class A which is 94
b) Incorrect: The average of Class A is 84 which is higher than Class B is 76
c) Correct : The average of Class A is 84 which is higher than Class B is 76
d) Incorrect: The difference between highest and lowest scores in Class A is 16(94-78) whereas in Class B its 20(88-68)
A. The relation is a function if one x-value goes out to one <em />y-value. We can check the graph for that. Does any x-value come out to more than one y-value? No, so, therefore, yes, the relation is a function.
B. The domain is all the x-values shown in the relation. Therefore, it is Domain:{-4, -3, -2, 0, 2, 3}
C. Like the domain question, it is the y-values shown. Therefore, the range is Range: {2, 0, -1, 2, -3, 3}
D. The value of y is at x=2 is the y-value of the point that it shows in the relation when x = 2. We find the point where x=2 (the fifth one from the left), and the y-value there is -3
