Answer:
(-∞, -2) ∪ (-2, 6) ∪ (6, ∞)
Explanation:
The domain describes the x-values that can be used in a function.
The leftmost function contains all x-values until x = -2. This looks like (-∞,-2). Remember, open dots mean that the associated x-value is not included in the domain.
The middle function contains all x-values from x = -2 to x = 6. This looks like (-2, 6).
The rightmost function contains all x-values after x = 6. This looks like (6, ∞).
A time graph reveals specific information on the velocity (change in position with respect to a change in time).
So, on a position - time graph, the feature representing motion in the negative direction over time is a downward sloping line segment.
A slope in a position time graph depicts the velocity also called the slope in this type of graph as it the change in position over time.
So, a downward sloping line segment feature in a time graph indicates that the motion of the object is in the negative direction. While a positive sloping line segment indicates otherwise.
