Which of the following functions best describes this graph? O A. y = (x + 5)(x-3)
B. y = x2 +7x +10
O c. y = (x-2)(x-5)
O D. y = x2 + 5x+12

Asystem of equations has 1 solution. if 4x-y=5 is one of the equations , which could be the other equation ?

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
