The value of polygons.

Which equation is y = -6x2 + 3x + 2 rewritten in vertex form?

Which of the following is best modeled using a linear equation y=ax+b, where a is less than 0?

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
