Trigonometry
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?
Translate the graph of y = cos x by π/4 unit to the right, stretch it vertically by a factor of 5, and translate it by 14 units downward.
Translate the graph of y = cos x by π/4 unit to the right, compress it vertically by a factor of 5, and translate it by 14 units downward.
Translate the graph of y = cos x by π/4 unit to the right, stretch it vertically by a factor of 5, and translate it by 14 units upward.
Reflect the graph of y = cos x across the x-axis, stretch it vertically by a factor of 5, and translate it by 14 units upward.
