A baseball is dropped from an airplane 500 feet above the ground. The height
(in feet) above the ground is modeled by the function h(t) = -167 + 500,
where t is the time in seconds.

A What is the height of the ball after 2 seconds?
B how long will it take for the board to fall to a height of 100 feet above ground?
C how long will it take the ball to reach the ground

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
