\

Observe the graph of function, the coordinates points are $\"\"$ .

\

To find the suitable equation of the graph, substitute any coordinate point on the graph in the suitable equation.

\

Substitute the coordinate values $\"\"$ for x and y in the equation $\"\"$ .

\

If $\"\"$ then $\"\"$ (This is true)

\

If $\"\"$ then $\"\"$ (This is not true)

\

Therefore the equation $\"\"$ is not suitable for the graph. $\"\"$

\

Substitute the coordinate values $\"\"$ for x and y in the equation $\"\"$ .

\

If $\"\"$ then $\"\"$ (This is true)

\

If $\"\"$ then $\"\"$ (This is not true)

\

Therefore the equation $\"\"$ is not suitable for the graph. $\"\"$

\

Substitute the coordinate values $\"\"$ for x and y in the equation $\"\"$ .

\

If $\"\"$ then $\"\"$ (This is true)

\

If $\"\"$ then $\"\"$ (This is true)

\

If $\"\"$ then $\"\"$ (This is true)

\

If $\"\"$ then $\"\"$ (This is true)

\

If $\"\"$ then $\"\"$ (This is true) $\"\"$

\

Substitute the coordinate values $\"\"$ for x and y in the equation $\"\"$ .

\

If $\"\"$ then $\"\"$ (This is true)

\

If $\"\"$ then $\"\"$ (This is not true) $\"\"$

\

The option C is correct answer.
