Answer:
The positive difference between the a values is 0.5
Explanation:
we know that
Both parabolas cross the x axis at (-4,0) and (6,0)
so
The general equation is

Find the value of a in the first parabola
The y-intercept is (0,-12)
so
For

substitute




Find the value of a in the second parabola
The y-intercept is (0,-24)
so
For

substitute




Find the positive difference between the a values for the two functions
so
