Suppose (x, y)=xy(1−10x−y).f(x, y) has 4 critical points. List them in increasing lexographic order. By that we mean that (x, y) comes before (z, w) if x

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
