Usually for Enlargement/Reflection questions it get to be a shape on the graph as a rectangle, hexagon..etc. whenever we enlarge an image we usually multiply the vertices of the shape by the enlargement Factor or matrix to get the new set of prime points forming a shape.
OKAY what if this time in the external the shape was a circle...
and the question states to enlarge it using a certain factor or matrix for instance by then we really can't just multiply vertices......because it's rounded what shall we do in this case??
Thank you help is appreciated.
the points of the circle will have co-ordinates on the graph, use 2 co-ordinates,for example, one on the extreme left and extreme right of the circle, and get the new position of the points. then draw a circle using these two points with a circle.
