Chapter 2.5, Problem 35E

In Problems 30–35, the length of a plant, L, is a function of its mass, M, so L = f(M). A unit increase in a plant’s mass stretches the plant’s length more when the plant is small, and less when the plant is large. Assuming M > 0, decide if $f\text{'}$ agrees with this description.

$f\text{'}\left(M\right)=0.25M/M^{3/4}$
