A quadratic equation is usually of the form:
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.
