Answer:
Step-by-step explanation:
Looking at the graphs we can state that:
A) Not a function as it fails the vertical line test. The three points has same x-coordinate of -1.
B) Not a function as it fails the vertical line test. The three points has same x-coordinate of 1.
C) Is a function as each x-value has a unique y-value:
- (-3, 2), (- 1, 1), (0, - 3), (4, 1)
- Passes the vertical line test
D) Is a function as each x-value has a unique y-value:
- (-3, -2), (-2, - 1), (0, 3), (1, 0), (2, - 3)
- Passes the vertical line test
