Provide an appropriate response.Graph y = - tan x and its derivative together on 
. Is the slope of the graph of 
ever positive? Explain.
What will be an ideal response?
No, the slope of the graph of 
is never positive. The slope at any point is equal to the derivative, which is 
. Since sec2 x is never negative, 
is never positive, and the slope of the graph is never positive.
