Write an Equation for the Function That Is Described by the Given

question 8

Multiple Choice

Write an equation for the function that is described by the given characteristics. ​
A sine curve with a period of 4π,an amplitude of 4,a left phase shift of $\frac { \pi } { 4 }$ ,and a vertical translation down 5 units.
​

• A) \(y = 4 \sin \left( x + \frac { \pi } { 8 } \right) - 5\)
• B) \[y = 4 \sin \left( \frac { x } { 2 } + \frac { \pi } { 8 } \right) + 5\]
• C) \[y = 4 \sin \left( \frac { x } { 2 } + \frac { \pi } { 8 } \right) - 5\]
• D) \(y = 4 \sin \left( \frac { x } { 2 } + \pi \right) - 5\)
• E) \(y = 5 \sin \left( \frac { x } { 2 } + \frac { \pi } { 8 } \right) - 4\)
