The range of a function is the set of numbers used as y-coordinates.
Let's look at the y-coordinates of the points in the graph.
There are points in the graph with all y-coordinates greater than -3.
There are points in the graph with all y-coordinates less then -3.
At exactly -3, there is no point on the graph with that y-coordinate.
We expect the graph to behave as it is shown above 7 and below -7, so the only value excluded from the y-coordinates is -3.
Answer: B. All real numbers except -3
I think The last one in right
y |2| 6 |10 |14
x |6 |18 |30 |42

Answer:
The answer to your question is: Yes a parabola can be drawn if we know the focus and the directrix.
Step-by-step explanation:
We can say that it is a vertical parabola that opens downwards.
We conclude that if we graph both the focus and the directrix. Also if we continue the process we can find the vertex (-4, -7) and p = 3.
