David graphs a polynomial function with the features listed below. • Zeros at x = -1, x = 2, and x = 3
y-intercept at (0, -6)
End behavior of f(x) = 0 as x - -- and F(X) - -o- as X – 0
Which function did David graph?
.
A. f(x) = x + 4x +x-6
B. f(x) = -x + 4x? – X-6
o C. f(x) = -x - 4x - x + 6
o D. f(x) = x°- 4x + x + 6

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
