Answer:
vertex: (-2, 4)
Step-by-step explanation:
Use your regression calculator to find the parameters of the quadratic model.
The vertex form equation is ...
y = -3(x +2)^2 +4
so the vertex is (-2, 4).

The standard form equation is the expansion of the above:
y = -3x^2 -12x -8
Answer:
f = 
Step-by-step explanation:
Given
b = fjn ( isolate f by dividing both sides by jn )
= f
Y = 1/2x - 5
We know the slope to be 1/2 because lines that are parallel have the same slope. Then we can solve using slope-intercept form and the known point.
y = mx + b ----> Input known values
-2 = (1/2)(6) + b ---> Multiple
-2 = 3 + b ----> Subtract 3 from both sides
-5 = b
Now we can use the y-intercept found and the slope to write the equation above.
