Graphing Word Problems

This question comes from a student in the Reason Prep Study Group:

You might want to give this one a shot on your own first before watching this video:

In this video I give the solution for this particular problem and give three general strategies that you can use, in conjunction with process of elimination, to attack other questions of this type:

  1. Think of maximum & minimum, starting & ending points to eliminate choices.
  2. Look for “trends” (rates of change) that might help you eliminate more choices.
  3. Draw the figure & plots the points to narrow down to the final answer.
