Biology: A biologist has found that the number of branches on a certain rare tree can be modeled by the polynomial b(y) = 4y2 + y where y is the number of
years after the tree reaches a height of 6 feet. The number of leaves on each
branch can be modeled by the polynomial L (y) = 2y3 + 3y2 + y . Write a polynomial describing the total number of leaves on a tree
polynomial describing the total number of leaves on the tree.
