(Technology required to create a best-fit quadratic.) When people meet for the first time, it is customary for all people in the group to shake hands. Below is a table that shows the number of handshakes that occur depending on the size of the group. a. Draw a scatterplot of the data in the table (with group size on the horizontal axis) and find a quadratic model of best fit. b. Use the model to find the total number of handshakes for a group of seven people and for a group of ten people. c. Factor the model of best fit. Describe in words how you could find the number of handshakes knowing the group size.
