help because I dont know how to do one demsion lines or the stability. Also how do I do growth rate of the phase lines for question 1?

In Exercises 1-11, graph the one-dimensional phase lines. In doing so, determine all equilibria and their stability. 2. dx dt =x(x - 1)2. 10. dx dt -x3.1. Consider d.x dt = ax - bx (with a > 0, b > 0, and x 2 0). a) How does the growth rate depend on the population? b) Sketch the one-dimensional phase line
