Can someone write me the matlab code for this? I tried VERY hard but I am absolutely clueless and keep getting errors

AT&T 4G 7:57 PM @ 41% 23. Consider y' = (a-1)V-3 3, Explain why y = 0 is the only 1, and why there are three distinct real roots when a > 1. (a) Use solve to find the roots of (a-1) (b) For =-2,-1, 0, draw a direction field for the differential equation and (c) Do the same for 1. real root when deduce that there is only one equilibrium solution. What is it? Is it stable? (d) For = 1.5, 2, draw the direction field. Identify all equilibrium solutions, and describe their stability. (e) Explain the following statement: "As a increases through 1, the stable solution y 0 bifurcates into two stable solutions
