The diffrential equation is $\"\"$ .

(1).Draw the coordinate plane.

(2).Graph the diffrential equation $\"\"$ .

Graph :

$\"\"$

Observe the graph :

The diffrential equation $\"\"$ represents the graph $\"\"$ .

Explanation :

If $\"\"$ then $\"\"$ , since $\"\"$ satisfies the condition the match will be either $\"\"$ or $\"\"$ .

The output depends on the value of $\"\"$ .

Since graph $\"\"$ match with the previous solution ,the answer will be graph $\"\"$ .

$\"\"$

The correct choice is $\"\"$ .
