A tree branch is observed to bend as the fruit growing on it increase in size. By estimating the mass of the developing fruit and plotting the data over time, a student finds that the height h in metres of the branch end above the ground is closely approximated by the function h=2-0.2×1.60.2m where m is the estimated mass, in kilograms, of fruit on the branch.
