Answer the questions on each screen. The correct answer will be shown on the screen following each question. If

someone in the class needs an explanation, someone in the class that worked the problem right can come, show their

work under the document camera and explain it to the class.

Use the quadratic formula to solve the equation.

After how many seconds will the ball reach its maximum height? And, what is the maximum height?

A ball is thrown directly upward from an initial velocity of 96 feet per second. The height of the ball as a function of time can be modeled by the function

Hint: If we are looking for maximum height then we must be finding the vertex.

14)

The axis of symmetry is x = 3. Plug 3 back into the

equation for the vertex and you get

(3, 344) Therefore the maximum height is 344 feet.
