Sinusoidal Function Parameters (4 Params) - Function to Parameters

Question

What are the vertical shift, phase shift, period, and amplitude of this sinusoidal function?

$$f(x) = -4\cos (\frac{2}{7} \pi x+\frac{3}{7})+\frac{8}{7}$$

Accepted Answer

$$	ext{Amplitude } = 4 \	ext{Period } = \frac{14}{2} \	ext{Phase Shift } = \frac{3}{7}  	ext{ left} \	ext{Vertical Shift } = \frac{8}{7} \$$

Answer

$$	ext{Amplitude } = 4 \	ext{Period } = \frac{14}{2} \	ext{Phase Shift } = \frac{3}{7}  	ext{ right} \	ext{Vertical Shift } = \frac{8}{7} \$$

Answer

$$	ext{Amplitude } = \frac{2}{7} \	ext{Period } = \frac{2}{4} \	ext{Phase Shift } = \frac{3}{7}  	ext{ left} \	ext{Vertical Shift } = \frac{8}{7} \$$

Answer

$$	ext{Amplitude } = 4 \	ext{Period } = \frac{14}{8} \	ext{Phase Shift } = \frac{3}{7}  	ext{ left} \	ext{Vertical Shift } = \frac{2}{7} \$$
