An object moves in simple harmonic motion with period 5 minutes and amplitude 17 m. At time t=0 minutes, its displacement d from rest is -17 m, and initially it moves in a positive direction.

Give the equation modeling the displacement d as a function of timer t.

Which of the statements about the graph of the function y = 2x are true? check all of the boxes that apply. the domain is all real numbers x because the exponent of 2 can be any real number when the x-values increases by 1 unit, the y-value multiplies by 2. the y-intercept is (0, 1). the graph never goes below the x-axis because powers of 2 are never negative. the range is all real numbers.
