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 -values are on the other side.

Integrate both sides of the equation.

Solve for . Did you get a cubic function, as predicted?
