Which of the following statements correctly describes the procedure for obtaining the graph of y = -14 + 5 cos (x - π/4) from the graph of y = cos x?

Graph the following function. Consider two periods.

$y=\sin\left[2\left(x+\frac{\pi}{6}\right)\right\rbrack+\frac34$

Find the amplitude and period of the given function and sketch its graph for one period. 

y = 11 sin 2x

Graph the function for 0 ≤ x ≤ 2π by performing the addition of the y-coordinates

y = cos x + 3cos 2x

Draw the graph of the function given below on $\left[-2\pi,2\pi\right\rbrack$ . Use the graph to find the amplitude.

$y=-5\sin x$
