A soccer ball is kicked into the air, and its path can be modeled with a quadratic function. The table shows the time, t, in seconds, and the height of the soccer ball, h, in feet. Follow the steps to write the function. 1. Identify x-intercepts: (0, 0) and (5, 0) 2. Use factored form: f (t) = a (t - 0) (t - 5) f (t) = at (t - 5) 3. Find the value of: 12 = a (3) (3 - 5) 4. Write function: f (t) = t (t - )

    The y-intercepts are

    (0,0) and (5,0)

    The equation of the quadratic function is

    f (t) = at (t-5)

    Solving for a

    12 = a (3) (3-5)

    a = - 2

    The equation of the quadractic function is

    f (t) = - 2t (t - 5)

    f (t) = - 2t² + 10t

    -2 and - 5

    f (t) = - 2t (t - (-5))
