Answer:
The correct option is 3. The best approximate for the given graph is [tex]\sqrt{28}[/tex].
Step-by-step explanation:
From the given graph it is noticed that the point lies between 5 and 6.
Let the square root of x is the best approximate for the given graph.
[tex]5<\sqrt{x}<6[/tex]
Taking square on each side.
[tex]5^2<(\sqrt{x})^2<6^2[/tex]
[tex]25<x<36[/tex]
It means the value of x lies between 25 to 36 and the graph represents the approximate value between [tex]\sqrt{25}[/tex] to [tex]\sqrt{36}[/tex].
Therefore best approximate for the given graph is [tex]\sqrt{28}[/tex]. Option 3 is correct.
