Answer:
y= 4 sinx/2-3
Explanation:
y= a sin2πt/T
where : a is the amplitude , t is the time in seconds, and T is a period of wave is seconds.
y=A sin (B(x+C)) +D
amplitude A = 4
2π/B is period = 4
C is the phase shift = -2
D is vertical shifts = -2
now substitute the numbers in the equation :
y= A sin ( B(x+C)) + D
y= 4 sin (4(x-2) -2
y=4sin(4x-8)-2
