A restaurant serves between 100 and 200 people every evening. Each customer buys either the 'Meal of the Day' at $20 or the 'Gourmet Meal' at $40. No more than 25% of the customers on any evening buy the 'Gourmet Meal'. All drinks cost $5, and everybody has at least one drink, but nobody ever has more than four.

step-by-step explanation:

to determine whether a given function is even, we simply substitute x with -x in the expression. if the result after simplification is identical to the original equation, then the function is said to be even other wise odd.

f(-x) = (-x)^2 - (-x) + 8

      = x^2 + x +8

the resulting function is not identical to the original one;

f(-x) ≠ f(x)

therefore, f(x) is not an even function

(53.5 - 18.4) m.

step-by-step explanation:

after undergoing a displacement of 18.4m, the initial position was (53.5 - 18.4) m if an object has a final position of 53.5.
