Given information

Given:

Differential equation:

                                                

 

 

Step-by-step explanation

Step 1.

Concept used:

If  then, slope of graph will be flat at that point.

The slope of the graph will be increasing or decreasing according to 

 

In equation (i) cannot be negative and can never be negative.

i.e. can never be negative.

It implies that other than

As a result, the graph's slope cannot be negative.
However, we can see in the first graph that the slope of the graph is negative at one point. As a result, the graph I cannot be the differential equation's solution.
