Question 6 1 pts
A softball player stands at a point that is modeled by (0,0) on the coordinate plane. She then
throws a softball that is modeled by a quadratic equation. Select two key features that help
determine the vertical height that the softball traveled from when it left the softball player's
hand to when it reached its maximum height.
m end behavior
m vertex
zeros
y-intercept

125 yards

step-by-step explanation:

i take 75 plus 50.

step-by-step explanation:

1. when "a" is a root of a polynomial, (x -a) is a factor of it. for the three roots given, the factors of the desired polynomial are (x +2)(x -1/2)(x -3).

in order to make the leading coefficient be negative, we need to multiply this product by a negative number. any negative number will do, but we choose a small (magnitude) value that will eliminate the fraction: -2.

then

f(x) = -2(x +2)(x -1/2)(x -3) = -(x +2)(2x -1)(x -3)

= -(2x² +3x -2)(x -3)

= -(2x³ -3x² -11x +6)

f(x) = -2x³ +3x² +11x -6

2. a graph created by the desmos on-line graphing calculator is shown, and the zeros are highlighted.

3. as indicated in part 1, the multiplier of this equation can be anything and the zeros will remain the same. you want a negative leading coefficient, so the "anything" is restricted to any of the infinite number of numbers that will make that be the case.
