Considering the vertex of the graph, it is found that the quadratic function that is the best model for the data is given by:

<h3>What is the equation of a quadratic function given it’s vertex?</h3>
The equation of a quadratic function, of vertex (h,k), is given by:

In which a is the leading coefficient.
Researching the problem on the internet, it is found that the vertex is at point (4,800), hence h = 4 and k = 800.

It has a value of y = 0 at x = 6, hence:


Thus, the model is:

Answer:
3.5555555555556
Step-by-step explanation:
you cannot find the Mean Absolute Deviation of one number. This answer is the data set 2, 9, and 0. 3.5555555555556 is the Mean Absolute Deviation of 2, 9, 0.
Answer:
12 inches = 1 foot
9,944 inches = 9,944/12 = 826.67 ft
Yap,
It seems to me that there are two answers. Both y = .5x and y = 12x. Direct variation is what I'm thinking of so hopefully this helps.
BTW - with Direct Variation, the line will go through (0, 0).
