2. a scientist wants to predict the affect of a rise of global air temperature on the sea level
around the world. which method, a controlled experiment, a scientific investigation or a
scientific model would be most useful to set up? why?

is there a question here?

step-by-step explanation:

15.36 per mile

but forgot to round

i am pretty sure

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
