A horse gallops a distance of 60 m and 15 seconds. Then, he stops to eat some grass for 20 seconds. Next, he trots for 25 seconds over 60 m. The horse trots in the same direction he galloped. Finally the horse races back home (back to it starting position) traveling 120 m in 20 seconds. Calculate the horses average speed for the entire journey.

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
