Answer:
D = {x|x∈R|x≥-4}
R = {y|y∈R|y≥-2}
Use the vertex to determine the domain and range.
The outside of the root is positive so it continues upward. [y = -√x the graph goes down from vertex.]
The inside of the root is positive so it continues rightward, [y=√-x the graph goes left from vertex.]
In the equation y = √(x + 4) – 2, the vertex is (-4, -2). The x-coordinate of the vertex is negative the value in the root.
3 and 2/3 hours.
Multiply the number of hours Dominic spent by the scale factor.

Answer:
Option C = ![y = \sqrt{2x-6} + 1](https://tex.z-dn.net/?f=y%20%3D%20%5Csqrt%7B2x-6%7D%20%2B%201)
Step-by-step explanation:
As you can see from the graph, one of the points lying on the graph is (3,1).
Inserting this point in above all equations, we get,
1] <em>
= -1</em> , which is not equal to 1.
2]<em>
</em>= 4.464 , which is not equal to 1.
3]<em>
= 1</em> , which is equal to 1.
4] <em>
= 2.464</em> , which is not equal to 1.
Thus, only option 3 satisfies the point.
One can also check for other points.
