Help me please I need to get this right to complete

Answer 1

Answer:

[-6, 8]

Step-by-step explanation:

Domain: set of all possible input values (x-values)

Range: set of all possible output values (y-values)

The closed circles on the endpoints of the curve mean that those points are included in the interval.

From inspection of the graph, the smallest y-value is -6 and greatest y-value is 8.  

To express this in interval notation write the beginning and ending numbers of the interval inside square brackets as the end values are included.  

(If the circles were open, and therefore the end values should not be included, use curved brackets).

Therefore the range of the given graph is:  [-6, 8]
