What is the equation of the quadratic function with a vertex at (2,-25) and an x-intercept at (7.0)?
f(x) = (x - 2)(x - 7).
f(x) = (x + 2)(x + 7)
f(x) = (x - 3)(x + 7)
f(x) = (x + 3)(x – 7)

Astudent draws two parabolas on graph paper. both parabolas cross the x-axis at (-4, 0) and (6,0). the y-intercept of thefirst parabola is (0, –12). the y-intercept of the second parabola is (0-24). what is the positive difference between the avalues for the two functions that describe the parabolas? write your answer as a decimal rounded to the nearest tenth.
