Investigating Scale Factor Using the NSpire 1)Use the Nspire to construct a rectangle using the rectangle tool. 2)Then scale the rectangle by scale factors: a) 2b) 3c) ½ d) 1e) ¼ 3) What conclusions can you draw if: a) The scale factor is greater than 1? b) The scale factor is between 0 and 1? c) The scale factor is 1?
