Solve the problem.The graph shows the amount of potential energy V(x) (in arbitrary energy units) stored in a large rubber band that is stretched a distance of x inches beyond its relaxed length. src="https://sciemce.com/media/4/ppg__dsd0601191643__f1q119g4.jpg" alt="" style="vertical-align: -4.0px;" /> (Hint: the force in this problem has units of "energy units per inch".)
A. 3.6 energy units per inch
B. 2.5 energy units per inch
C. 0.3 energy units per inch
D. 4.3 energy units per inch
The magnitude of the force required to hold the rubber band at the position 
is the derivative of the potential energy with respect to x, evaluated at the point 
Estimate the force required to hold the band at a stretched position
