9. Assuming that an airport’s service area includes all of the cities that are closer to it than to any other airport, determine how many cities each airport serves. Which airport serves the most cities? How many cities? Which serves the most people? How many people? Sort and examine the POP2000 field in the cities feature class. What do you need to do to ensure that you have the correct answer for the number of people served?

1: -2 3/4, -2 1/2, -14, 0, 3, 8 1/3

2: -4, -3, -2 1/2, -2 1/4, 3 1/4,

step-by-step explanation:

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
