Unit 2, Activity 2,Discovery using Technology Blackline Masters, Advanced Math-PreCalculusPage 53 Louisiana Comprehensive Curriculum, Revised 20081. Plot on the same screen the following graphs: ,2xy=,3xy=y = x4, y = x5a) What points do all of the graphs have in common? b) Which function increases most rapidly, and which increases least rapidly, as xbecomes large? c) What are the main differences between the graphs of the even powers of x and the odd powers of x? 2. Plot on the same screen the following graphs: ,2xy−=,3xy−=y =-x4, y = -x5a) What characteristics do these graphs share with the graphs in #1? b) How do these graphs differ from the graphs in #1? 3. Plot on the same screen the following graphs: ,2xy=y= 4x, xxy42+=a) What do you notice about the graphs of 2xy=and xxy42+=when xis a large positive or negative number? b) What do you notice about the graphs of y= 4x and the graph of xxy42+=when xis a small positive or negative number?
