I need help with my homework .... It is passed due I have to get it done. If not I will get a F on it ... Please help me with it

Answer 1

a) see attachment for graph

b) D: [0, 2.5]    time cannot be negative so the x-values start at 0

   R: [0, 100]    height cannot be negative so the y-values start at 0

c) 84 ft             refer to the red coordinate on the graph

d) 1.75 seconds   refer to the blue coordinate on the graph

e) 2.5 seconds     refer to the green coordinate on the graph

When looking for coordinates at the various given values, remember that x is time and y is height.  

• If you are given time, then look at the y-value for height
• If you are given height, then look at the x-value for the time.
