Answer:
amplitude = 3
period = [tex]\frac{2\pi }{3}[/tex]
Step-by-step explanation:
Comparing the equation with the general equation :
[tex]f(x) = A cos(Bx + c ) + D[/tex]
Where :
A = amplitude
period = [tex]\frac{2\pi }{B}[/tex]
D = vertical shift
Therefore : with the comparison :
amplitude = /-3/ = 3
period = [tex]\frac{2\pi }{3}[/tex]
