A train travels at a constant speed for a long distance. Compete the two statements that describe the constants of proportionality for the relationship between distance traveled and elapsed time. Express fractions in the form a/b. Part A:
The train travels (?) miles in 1 hour.

Part B:

It takes (?) hours for the train to travel 1 mile.

multiply each one by 3.14

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

is it like a multiple choice? if so then i need the multiple choice so i can get and understanding on what the answers is so that i can explain it to you
