Answer:
The vertex is at (-1,-7).
The answer to 2 is A.
Step-by-step explanation:
<h3>1st of all, for the vertex:</h3><h3 />You want to make the absolute value be |0|, and you make that by assuming a x that is the opposite of the number that accompanies it.
In this case:
Because:
Then:
And, by making the absolute value equal 0 when finding x, you're left with:
The easiest way is to graph, or make a table of values and see where the graph points.
I graphed it for you.
You can clearly see how the vertex, at (-1,-7) is the lowest point, telling you that the range is from that point upwards, or
Then, because you're dealing with absolute values, which never bend and make perfect 90° angles at their vertex, it is safe to assume both lines never touch and continue to opposites ends of the x-axis, or (-infinity, infinity) which is your domain.
