    Quadratic Functions - Test Tomorrow

    What do the different things in an equation mean?

    Problem:
    Napoleon fires a cannonball into the air. The height, h meters, of the cannonball above the horizontal ground, t seconds after launch is given by the equation.
    h=-4t^2+15t+9

    What does ax^2 mean? What does bx mean? What does c mean?

    I'm supposed to find out what information is represented by the constant 9 in this context but I dont know what any of the information represented is?

    Please help me.

    Thank you so much.

    Constants called "coefficients".
    It can be any number you want.
