Answer:
option A.
Explanation:
if the blue dots represent the function it's domain will be the values of x for which a blue dot is raised.
The "points" have coordinates:
- (0, 4)
- (-6, 1)
- (2, -5)
- (4, 3)
- (7, 3)
Now, the abscissa, I.e., the x coordinate of a point represents its domain, while the ordinate, I. e., the y coordinate represents its range.
Therefore,
Domain:
{0, -6, 2, 4, 7}
Range:
{4, 1, -5, 3}
That is, option A!
