Step-by-step explanation:
Explaining the sine function:
The sine function is defined by:
In which A is the amplitude, is the period,
is the horizontal shift and V is the vertical shift.
So, in your problem:
The amplitude is 4, so A = 4.
The period is , so
.
There is no horizontal shift, so .
The vertical shift is −3, so V = -3.
The sine function that represents these following conditions is
, the third one
