    Question algebra question with a table and I need an quadratic equation

    Q: a boy threw a baseball in the air. The following table shows the height of the baseball in 1 second intervals.
    Time (seconds) Height(feet)
    0 0
    1 10
    2 20
    3 10
    Based on the quadratic model, which best approximates the height at 1.25 seconds?

    A 6.5
    B 7.5
    C 12.8
    D 15

    Re: algebra question with a table and I need an quadratic equation

    "Based on the quadratic model" means trying height equal to h(t)= at^2+ bt+ c for some numbers a, b, and c. Use three of the t and h values you are given to get three equations to solve for a, b, and c. Then evaluate h for t= 1.25.
