Amplitude is 1
Period is halved and is now
No phase shift has happened
Explanation:
A~Vertical stretch (Amplitude)
B~Horizontal stretch (period)
C~Horizontal translation (phase shift)
D~Vertical translation
So the A is 1 which means the amplitude is 1
So the B is 2 which means the period is halved so it is
So the C is 0 which means it hasn't been phase shifted
So the D is 0 which means it hasn't been upwards
