Answer:
see the procedure
Step-by-step explanation:
Looking at the graph we have
The graph represent a vertical parabola open upward
The vertex is a minimum
The vertex is the point (-4,-3)
The domain is the interval -----> (-∞,∞)
The Domain is all real numbers
The range is the interval ----> [-3,∞)

The range is all real numbers greater than or equal to -3
The graph is increasing in the interval (-4,∞)
The graph is decreasing in the interval (-∞,-4)
The minimum of the graph is y=-3 occurs at x=-4
The domain is {8, 9, 10, 11, 12}.
The domain is the set of input values; in this function, the input values are u, the number of uniforms. If there are at least 8 but no more than 12 players, they will need between 8 and 12 uniforms. We will only use whole numbers for this, since we will not have pieces of uniforms. This means the whole numbers between 8 and 12 will make up the domain.
