Atree of height y meters has, on average, upper b branches, where upper b equals y minus 3. each branch has, on average, n leaves where n equals 2 upper b superscript 2 baseline minus upper b. find the average number of leaves on a tree as a function of height.

we are given

number of branches is

number of leaves on each branch

the average number of leaves = (number of branches)*(number of leaves on each branch)

so, we can plug values

we get

now, we can plug values

now, we can simplify it
