Answer 1

The function f(x) = -2(4)²+1 +140 represents the number of tokens a child has x hours after arriving at an arcade.

The practical domain of the situation is all real numbers, since there is no restriction on the number of hours the child can spend at the arcade.

The practical range of the situation is [1,140], since the minimum value of the function is 1 and the maximum value is 140.
