A child is 22 inches long at birth and grows to an adult height of 70 inches.
?
?
A: Make a logistic model of the height H, in inches, at age t years. Note: Thus far you are not given sufficient information to determine the value of r in the expression . Just leave that term as a variable.
?
B: In the model from part A we think of restricting the age to 15. That corresponds to putting
in the formula, so H is a function of r. Make a graph of H versus r with
. You may assume that r is no larger than 1.
