Answer:
The second choice
Step-by-step explanation:
In most cases, the dependent variable is the y value in the graph.
The dependent variable is the thing that is being measured or changing.
In this example it can't be the time because time is always moving at a constant rate and there is nothing that can be done to change it.

The parent function for quadratic equations is as followed:

where a for vertical stretches, b is for horizontal stretches, h is the x value of the vertex, and k is the y value of the vertex.
The vertex of the is (-3, -2), so we can write the first part of the equation:

To determine if the graph has any stretches, we can check how changes to the x coordinate affect the y value. If there are no stretches, as the x coordinate moves away from the vertex, the y coordinate should be x^2 from the vertex. If we test with a couple points on the graph, wee see that this is true, so there are no stretches. The answer is:
Answer:
Step-by-step explanation:
When the quadratic is written in vertex form:
x = a(y -k)^2 +h
the vertex is (x, y) = (h, k), and the length of the latus rectum is 1/a.
For your given equation, ...
x = (1/2)(y -5)^2 +7
you have a=1/2, k = 5, h = 7, so ...
the vertex is (7, 5)
the length of the latus rectum is 1/(1/2) = 2
