Answer:
A'(-4,-4), B'(-4,-1), C(-2,-3), D(-1,-1)
Step-by-step explanation:
After counterclockwise 90 degree rotation X and Y coordinate swap and X coordinate changes its sign
Rotation of 90° (CounterClockwise) (x, y) ----->(-y, x)
3 9/10,64,B,D
dy/dx =
-y + 2x²- x = -5y³
2x² - x = y - 5y³
4x - 1 = dy/dx - 15y².dy/dx
dy/dx(1 - 15y²) = 4x - 1
