What techniques have you learned for graphing? There are many different ways to do this.

"Domain" refers to t values. Phyiscally, what are the possible times here?b) What is an appropriate domain for this function?

Where was the ball when t= 0?c) How tall is the building?

What is x(2)?d) How high is the ball after traveling 2 seconds?

The ground is x= 0. Solve .e) When does the ball reach the ground?

What are the possible heights for the ball?f) What is the range of this function?

The ball in this example was "dropped" which means initial speed 0. If it is "thrown upward" what can you say about the initial speed?g) Another ball is thrown upward from top of the same building. Give an example of

a function G where G(t) gives the height of the ball form the ground after t

seconds.

I would feel better about these, and might be able to give more help, if you showed some sign of havingtriedthese your self. Do you understand that most of these problems require only integer arithmetic?
