How do you solve dy/dx=(y−1)(y+1) if the solution passes through the point (x, y)=(4,0)(x, y)=(4,0)?

i got y=(1+e^(2x-8))/(1-e^(2x-8)) but it was wrong: (

Polygons efgh and e′f′g′h′ are shown on the coordinate grid: what set of transformations is performed on efgh to form e′f′g′h′? a. a translation 1 unit to the left followed by a 90-degree counterclockwise rotation about the origin b. a translation 1 unit to the right followed by a 90-degree counterclockwise rotation about the origin c. a 90-degree clockwise rotation about the origin followed by a translation 2 units to the right d. a 90-degree clockwise rotation about the origin followed by a translation 2 units to the left
