Find a possible solution for y if
Then use the slope field for
By tracing a series of slopes, you should predict that the original function is cubic.
Separate the variables so that x-values are on one side of the equal sign and y-values are on the other side.
Integrate both sides of the equation.
Solve for y... Did you get a cubic function, as predicted?
Note: C1 + C2 = C3, or just C.
