Astudent draws two parabolas both parabolas cross the x axis at (-4,0) and (6,0) the y intercept of the first parabolas 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

X² + 4y² = 36 the major axis runs along: a) y=4x b) x-axis c) y-axis

Write each rational number in the form a/b, where a and b are integers. 1. 5 1/6 2. -12
