Which statement correctly identifies all three parameters of the function
$y = 4\sin(3x) + 7$ ?

Amplitude = 4, period = $3$ , midline $y = 7$

Amplitude = 4, period = $\dfrac{2\pi}{3}$ , midline $y = 7$

Amplitude = 4, period = $6\pi$ , midline $y = 7$

Amplitude = 7, period = $\dfrac{2\pi}{3}$ , midline $y = 4$
