Given information
Given that the graph
Step-by-step explanation
Step 1.
Since the graph of the function is symmetric about the y-axis so the graph of the derivative will be symmetric about the origin.
The graph of the function has a horizontal tangent at so derivative will be 0 at .
For , the graph of the function is decreasing so the derivative will be negative, and for , the graph of the function is increasing so the derivative will be positive.
