follow this formula (x,y)->(-y,x)
To find the image of the point (4, 3) after a 90-degree rotation counterclockwise about the origin, you can use the transformation formula for rotation. The new coordinates will be (-y, x), which means the image of the point (4, 3) will be (-3, 4).
Yes. The transformation from y = f(x) to y=f(2x) will compress the shape along the x-axis by a factor of 2.
depends on the centre of rotation if it's about the origin the x coord is multiplied by -1
The transformation from y = f(x) to y = f(x - 4) - 2
