This video continues with a new series that will feature one math question each day. For each question, pause the video and try to work out the solution yourself before resuming the video.
This problem focuses on finding the minimum value of a second degree polynomial. Completing the square and putting the function into its vertex form will make the minimum value clear. Also, finding the derivative and setting it equal to zero will work for finding the minimum value as well.
