How is the graph y=-1/2 (5)x-3 translated from the graph of y=1\2(5)x ?

For this case we have the following function:
 y = 1 \ 2 (5) ^ x
 We apply the following function transformations:
 Reflections:
 To graph y = -f (x), reflect the graph of y = f (x) on the x-axis. (Vertical reflection)
 y = -1 \ 2 (5) ^ x
 Horizontal translations
 Suppose that h> 0
 To graph y = f (x-h), move the graph of h units to the right.
 y = -1 / 2 (5) ^ (x-3)
 
 Reflection on the x axis.
 Horizontal movement 3 units to the right

My

x equals the total number of players that signed up. Then you  have to split this into 5 teams. 2 players end up not playing. This leaves you with 11 on each team.

Sample Response:

The equation could model a scenario determining the number of players on each team in a league of five teams, if 2 players have to be taken out of the possible players to be referees and to keep score. There will be 11 players on each team.
