|
A. |
Domain {-1,4,5,6}Range {-2,2,3} The relation is not a function. |
| |
|
B. |
Domain {-2,2,3} Range {-1,4,5,6}The relation is not a function. |
| |
|
C. |
Domain {-2,2,3} Range {-1,4,5,6} The relation is a function. |
| |
|
D. |
Domain {-1,4,5,6}Range {-2,2,3}The relation is a function. |

| |
|
 |
| |
|
A. |
The domain includes negative real numbers. The range includes all real numbers. |
| |
|
B. |
The domain includes just positive real numbers. The range includes all real numbers. |
| |
|
C. |
The domain includes all real numbers. The range includes all positive real numbers. |
