A family moves a table shown as rectangle EFGH by translating its 3 units left and 3 units down followed by a 90 degrees rotation about the origin. Graph E'F'G'H' show the new location of the table.

Astudent draws two parabolas on graph paper. both parabolas cross the x-axis at (–4, 0) and (6, 0). the y-intercept of the first parabola is (0, –12). the y-intercept of the second parabola is (0, –24). what is the positive difference between the a values for the two functions that describe the parabolas? write your answer as a decimal rounded to the nearest tenth
