Use a graphing utility to select the correct graph $y _ { 1 } \text { and } y _ { 2 }$ in the same viewing window. Use the graphs to determine whether $y _ { 1 } = y _ { 2 }$ .
Explain your reasoning.
$y _ { 1 } = \cos ( x + 6 ) , y _ { 2 } = \cos x + \cos 6$
A) No, $y _ { 1 } \neq y _ { 2 }$ because their graphs are different.
B) No, $y _ { 1 } \neq y _ { 2 }$ because their graphs are Same.
C) Yes, $y _ { 1 } = y _ { 2 }$ because their graphs are different.
D) Yes, $y _ { 1 } = y _ { 2 }$ because their graphs are same.
E) No, $y _ { 1 } = y _ { 2 }$ because their graphs are different.
