Final Speed challenge Open a document and save it with the name ‘Speed’ Make 1.1 a calculator page and 1.2 a graph page. In the calculator page, Do 143 * 6 Find all the solutions to = 0 . In the graph page, graph y = x2 – 5 and find its roots. When you are done, open a Notes page and write down your time.

Solutions 143*6 = 858 Solutions = -2, 0, ½, 1, 2 Roots = -2.24, 2.24
