Your friend's running speed is between 400 to 500 meters per minute. If she takes part in a 4000 m race,
what is the fastest time she could finish the race in?
t> - minutes

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol

answer: the answer is e

step-by-step explanation:

answer: (-6,3)

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
