Intro to Quadratic Equations Concepts

Which object was launched from a higher point?

1. Which object reached a higher point?

1. Which object was launched with the higher upward velocity?

1. Which object landed LAST?

The domain of the graph should only show values for time greater than zero.

Values for time = 3 make sense in this situation.

The height in feet of a thrown football is modeled by the equation f(t) = 6 + 30t - 16t², where time t is measured in seconds. What does the constant 6 mean in this situation?

1. The height in feet of a thrown football is modeled by the equation h(t) = 6 + 30t -16t², where time t is measured in seconds. The initial upward velocity of the football is ...

Two objects are launched into the air.

• The height, in feet, of Object A is given by the equation f(t) = 4 + 32t -16t².

• The height, in feet, of the Object B is given by the equation g(t) = 2.5 + 40t -16t².

• In both functions,  t is seconds after launch.

Which object was launched with a greater upward velocity?

The x- intercepts of the graph of the quadratic function defined by the expression (x + 6)(x - 6) are...
