During a research work, an effective and efficient way to follow the scientific method includes:
Make observations.
Ask questions.
Construct a hypothesis.
Test the hypothesis with an investigation.
Analyze the data.
Explain the result.
Communicate the result.
The scientific method is the variety of techniques that scientists use to observe, examine, investigate, and study the natural world and explain it based on evidence, theories, evidence, hypotheses, or factual information that scientists derive from their research work.
It can be defined as the scientific method usually involves combining traditional scientific processes with critical thinking, scientific knowledge, and reasoning to generate new ideas. Please note that if your hypothes is true, it should be shared with the community. However, if your hypothesis is wrong, you should build another hypothesis and repeat the process.

Answer:
The answer is "9"
Explanation:
In the given-question, the attachment file, which is "graph" is missing. so, in this question, firstly we add the file and then provide the solution:
please find the attachment of the image file.
Solution:
In the given graph by canceling, the out ends for getting the middle median that is equal to 2, that's why its value is equal to "9".
It should be one but if I’m wrong I am so so sorry
The value of 
is -3. 
<h2>Procedure - Differentiability</h2><h3 /><h3>Chain rule and derivatives</h3><h3 />
We derive an expression for by means of chain rule and differentiation rule for a product of functions:
![\frac{d}{dx}[f(x)\cdot g(y)] = [f'(x)\cdot \frac{dx}{dx}]\cdot g(y) + f(x) \cdot [g'(y)\cdot \frac{dy}{dx} ]](https://tex.z-dn.net/?f=%5Cfrac%7Bd%7D%7Bdx%7D%5Bf%28x%29%5Ccdot%20g%28y%29%5D%20%3D%20%5Bf%27%28x%29%5Ccdot%20%5Cfrac%7Bdx%7D%7Bdx%7D%5D%5Ccdot%20g%28y%29%20%2B%20f%28x%29%20%5Ccdot%20%5Bg%27%28y%29%5Ccdot%20%5Cfrac%7Bdy%7D%7Bdx%7D%20%5D)
![\frac{d}{dx}[f(x)\cdot g(y)] = f'(x)\cdot g(y) +f(x)\cdot g'(y)\cdot \frac{dy}{dx}](https://tex.z-dn.net/?f=%5Cfrac%7Bd%7D%7Bdx%7D%5Bf%28x%29%5Ccdot%20g%28y%29%5D%20%3D%20f%27%28x%29%5Ccdot%20g%28y%29%20%2Bf%28x%29%5Ccdot%20g%27%28y%29%5Ccdot%20%5Cfrac%7Bdy%7D%7Bdx%7D)
