The modeling function has period 0.8 seconds , amplitude 6 cm , and midline H = 15 cm .At time t =0.2, the bob is at its midline , moving towards the wall . Find the formula of the trigonometric function that models the distance H between the bob and the wall after t seconds. Defiance the function using radians .

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

the answer is z7+8/5
