Dear tatiana. Thank you for correcting us. Since the first derivative
is not equal to 0 for all real arguments, the number of relative
extremas in Problem 7 is 0. The maximum possible number of relative
extrema can be a minimum of 0 up to a maximum of 5-1=4.

the answer for number 7 is wrong. the answer is 4. the answer for the
maximum number of relative extremas is always the degree - 1. I got it
wrong on an assignment because of this :(
