1.  
   1. Complete a data table like the one shown for the quadratic function y = x2 + 2.
      
      
       

      x	0	1	2	3	−1	−2	0.5
      y

      
      
      Answer
      
      
   2. Draw a graph from the table of values in question 1.a. Join the data points in a smooth curve. You can use the graph paper provided, or you can search the Internet for a graphing tool. Answer
      
      

   3. Identify the x- and y-intercepts, if any, by looking at the graph. Answer

      
      
2.  
   
   1. Fill in a data table like the one shown for the quadratic function y = −5(x − 1)2 + 5, which describes the path of a quad during a jump.
      
      
       

      x	0	1	2	0.5	1.5
      y
