The position function of a car moving along a mountain road is given by the function f(t) = t3 - 2t2 + 4 kilometers, where t is in hours. What is the instantaneous velocity of the car at t = 2 hours? A.
3.00 km/hr
B.
4.00 km/hr
C.
4.41 km/hr
D.
5.21 km/hr

i believe it's a.

i'm not sure on this one, most likely correct.

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
