Exercises from Functions and Change: A
Modeling Approach to College Algebra
Growth: The length L, in inches, of a certain flatfish
is given by the formula
L  15  19  0.6t
and its weight W, in pounds, is given by the formula
W  (1  1.3  0.6t )3
Here t is the age of the fish, in years, and both formulas
are valid from the age of 1 year.

Exercises from Functions and Change: A
Modeling Approach to College Algebra
a. Make a graph of the length of the fish against its age,
covering ages 1 to 8.
b. To what limiting length does the fish grow? At what age
does it reach 90% of this length?
c. Make a graph of the weight of the fish against its age,
covering ages 1 to 8.
d. To what limiting weight does the fish grow? At what age
does it reach 90% of this weight?
e. One of the graphs you made in parts a and c should have
an inflection point, whereas the other is always concave
down. Identify which is which, and explain in practical
terms what this means. Include in your explanation the
approximate location of the inflection point.

Recommendations from The Mathe-
matical Education of Teachers
• Prospective middle grades teachers of mathematics should be required to take at least 21
semester-hours of mathematics, that includes
at least 12 semester-hours on fundamental
ideas of school mathematics appropriate for
middle grades teachers. [p. 8]
• One semester of calculus could be part of this
second group of courses if there is (or could be
designed) a calculus course that focuses on
concepts and applications, as opposed to the
traditional course offered to mathematics
majors and engineers. [p. 26]

Recommendations from The Mathe-
matical Education of Teachers
• Number theory and discrete mathematics can
offer teachers an opportunity to explore in depth
many of the topics they will teach.
• A history of mathematics course can provide
middle grades teachers with an understanding
of the background and historical development
of many topics in the middle grades curriculum.
• A mathematical modeling course, depending on
the level and substance of the course, can
provide prospective teachers with understanding of the ways in which mathematics can
be applied. [All p. 26]

Recommendations from The Mathe-
matical Education of Teachers
• Prospective middle grades teachers should:
 Understand and be able to work with algebra as a
symbolic language, as a problem solving tool, as
generalized arithmetic, as generalized quantitative
reasoning, as a study of functions, relations, and
variation, and as a way of modeling physical situations.
 Develop an understanding of variables and functions,
especially of different equivalent relationships between
variables.
 Understand linearity and how linear functions can
illustrate proportional relationships.
 Recognize change patterns associated with linear,
quadratic, and exponential functions.
 Demonstrate algebraic skills and be able to give a
rationale for common algebraic procedures. [p. 31]

Recommendations from The Mathe-
matical Education of Teachers
• Functions, relations, and variation all play
important roles in school algebra. In middle
grades these roles are prominent as students
come to understand algebraic functions,
particularly linear functions and the manner in
which they can illustrate proportional
relationships. Using qualitative graphs, that is,
graphs that have no numbers but that “tell a
story,” can lead to a deeper understanding of
functional relationships. [p. 31]

Recommendations from The Mathe-
matical Education of Teachers
• Middle grades teachers should know how to
deal with problems involving rate of change, for
example, of the growth of a plant, the decline of
an endangered species, or of the speed of a
car. The accumulation of miles traveled while
driving at a certain speed is also a problem of
change, and shows the relationship between
distance traveled and rate of travel (Noble,
Wright, Nemirovsky, & Tierney, 2001). [pp. 3132]
