Answer:
-2/3 < y < 0
Step-by-step explanation:
y = Asin(x)
Edit*
There's a node (y=0) at pi for sine wave. At 3/2pi will be the min. So range goes from -2/3 to 0
-1-4x+7x=1x+4x
-1-4x+7x=1x+4x
-1+-4x+7x=x+4x
(-4x+7x)+(-1)=(x+4x)
3x+-1=5x
3x-1=5x
3x-1-5x=5x-5x
-2x-1=0
-2x-1+1=0+1
-2x=1
-2x/-2=1/2
x=-1/2
