An object attached to a coiled spring is pulled down a distance a from its rest position and then released. Assuming that the motion is simple harmonic with period T, write an equation that relates the displacement d of the object from its rest position after t seconds. Also assume that the positive direction of the motion is up.a = 16;
T = 7 seconds

B. d = -16 cos 
C. d = -16 sin 
D. d = -16 cos 
Find the equation that the given graph represents and give the domain, range, and interval(s) over which the function is increasing and decreasing.
A. P(x) = -x5 - 3x2 + 6; domain: (-?, ?); range: [3.75, ?); Increasing over [-2.21, 0] and [2.21, ?); Decreasing over (-?, -2.21] and [0, 2.21] B. P(x) = x4 - 3x2 + 6; domain: (-?, ?); range: [3.75, ?); Increasing over [-1.24, 0] and [1.24, ?); Decreasing over (-?, -1.24] and [0, 1.24] C. P(x) = x5 + 2x3 + 6; domain: (-?, ?); range: [4.86, ?); Increasing over [-1.64, 0] and [1.64, ?); Decreasing over (-?, -1.64] and [0, 1.64] D.
