Title: College Algebra 6: Quadratic Functions
Book
Description: This
WorkBook is an introduction to quadratic functions, and quadratic growth.
It is full of experiments that will help you understand the ideas, beginning
with Galileo's law of freely falling bodies.
Other experiments include tossing a ball up with various velocities, and
applying the brakes to stop a car moving at various speeds. Different
representations for quadratic functions are explored, and the relations
of those representations to their graphs is developed through interaction.
Solving quadratic equations both by graphing, and algebraically are explored
next. For this, it generates quadratic equations randomly, or allows you
to make them up. In either case, it draws the graph and so displays the
solution graphically, then explains, step-by-step, how to solve the quadratic
equation algebraically. It does this for your problems also!
This is followed by a similar treatment of quadratic inequalities. Whether
you use an inequality it generates, or you make one up, it graphs the
inequality, and shows which interval(s) in the line provide(s) the solution,
by drawing that interval(s). Next, it gives a step-by-step explanation
of how the inequality can be solved algebraically.
