Eureka! We Found It!
As part of our school's Secretary Appreciation Day, students wrote a note of thanks to one of our school secretaries. These were delivered to them this afternoon.
Students shared their summaries about the relationship of a and b to the location of the line of symmetry and the vertex for a particular parabola. Most found that the line of symmetry was the opposite of half of the b value. This is true, but only when a = 1. We did a little bit more work on this and determined the formula for the line of symmetry to be x = - b/ 2a.
Tonight's Homework: Read pages 711-716 in the CME book, and then do problems 11 and 15 on page 719.
