Consider the ontogenetic model

(a) Determine all equilibrium solutions.

(b) Explain why

(c) Determine where in the region of physical interest the solution curves are concave up, and where they are concave down.

(d) Determine the slope of the solution curves at the point of inflection.

(e) Sketch the slope field and include some representative solution curves.
