question 56

Multiple Choice

Find the period P, amplitude A, and phase shift S, and graph at least two periods of the equation. $y = 8 \cos \left( \frac { 1 } { 4 } x + 210 ^ { \circ } \right)$

• A) P = 45°, A = 0.25, S = 26°
• B) P = 1,440°, A = 8, S = -840°
• C) P = 1,440°, A = 8, S = 840°
• D) P = 45°, A = 0.25, S = 26°
• E) P = 45°, A = 0.25, S = 26°
