Provide an appropriate response.Does the curve y = 
ever have a negative slope? If so, where? Give reasons for your answer.
What will be an ideal response?
The curve y = 
never has a negative slope. The derivative of the curve is y' = 
, which is never negative. A curve only has a negative slope where its derivative is negative. Since the derivative of y = 
is never negative, the curve never has a negative slope.
