Provide an appropriate response.For x > 0, sketch a curve y = f(x) that has f(1) = 0 and f'(x) = - . Can anything be said about the concavity of such a curve? Give reasons for your answer.

What will be an ideal response?




Since f"(x) =  > 0 for all x > 0, then the function is everywhere concave up.
