The correct axis of symmetry is x = -1.
Explanation:
Our equation is
.
This is in vertex form, which is
y = a(x-h)² + k, where (h, k) is the vertex.
In our equation, h corresponds with -1 and k corresponds with -3, making the vertex (-1, -3).
The axis of symmetry is the x-coordinate of the vertex; this makes the axis of symmetry for this equation x = -1.

Answer:
Step-by-step explanation:
Given the following question:
point A = (-3, -2)
point B = (2, 0)
To write the equation of the line that passes through two points we have to write the points in slope intercept form.
Formula for slope intercept:
M is equal to the slope of the two points, so first we need to fine the slope of the two points.
Hope this helps.
The initial value of the graph is where . Thus, in this case, the initial value is 12.
The rate of change of the graph is essentially the slope of the graph. In this case, we can use the slope formula:
and
are points on the graph
Let's use two points from the chart to find the slope:
In this case, the rate of change of the graph is 9.
