7-147.

Find a possible solution for if

Then use the slope field for

*(place your paper over the slope field and use the tangents as guides).*

By tracing a series of slopes, you should predict that the original function is cubic.

Separate the variables so that -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?

Note:

*, or just*
