Quadratic Formula Program
This program will display the solutions to quadratic equations or the words “No Real Solution.” To use the program,
write the quadratic equation in standard form and enter the
values of a, b, and c.

Reflections and Shifts Program
This program will sketch a graph of the function
where is an integer between
and 6, and is an integer between and 3. This
program gives you practice working with reflections,
horizontal shifts, and vertical shifts. Press after viewing the graph to display the values of the integers.
