4+3-1x22
4+3-22
7-22
-15
So -15 is the answer
Xy=20 As the width gets smaller, the length should get larger.
Answer:
The domain of the graph must be
.
Therefore,

Hence, option a is true.
Step-by-step explanation:
From the graph, it is clear that the graph is heading towards positive infinity from x=-4.
The point x=-4 is included in the graph as the starting point of the graph i.e. x=4 is showing a closed circle on x=4, and heading towards positive infinity onward.
i.e. [-4, ∞)
Hence, the domain of the graph must be
.
Therefore,

Hence, option a is true.
