Answer:
Step-by-step explanation:
12 - 4 = 8 ⇒ sin x is shifted 8 units up.
k = ( 12 - 4 ) ÷ 2 = 4
The abscissa is ( [tex]\frac{x}{2}[/tex] - [tex]\frac{\pi }{8}[/tex] )
y = 4 sin ( [tex]\frac{x}{2}[/tex] - [tex]\frac{\pi }{8}[/tex] ) + 8
Possible cosine equation is
y = 4 cos ( [tex]\frac{x}{2}[/tex] - [tex]\frac{\pi }{8}[/tex] ) + 8
