Answer: The maximum number of relative (local) extrema is 3.
Explanation: the polynomial is of 4th degree. Its derivative is a polynomial of a 3rd degree, which may have up to 3 roots (tied to extrema of the original polynomial). If all 3 roots are real each with multiplicity of 1, then the original polynomial will show 3 relative extrema.

Step-by-step explanation:
The record is the height per day, increase in growtb( height) every day .
MASS*GRAV*HEIGHT=PE
MASS=3
GRAV=9.8
HEIGHT=4.5
3*9.8*4.5=132.3
POTENTIAL ENERGY= 132.3
