Today’s Objective: I understand how changing a function is reflected in its graph.
Center of Dilation The center of dilation is a fixed point in the plane about which all points are expanded or contracted.
Let’s Review Dilations: a transformation retains the shape has a different size has a center of dilation and a scale factor k > 1, the image is an enlargement 0 < k < 1 the image is a reduction Notation (k): 𝒙,𝒚 →(𝒌𝒙,𝒌𝒚)

the moving of a point, shape, or graph Translation: the moving of a point, shape, or graph without rotating it or flipping it.
Translating a Point: Add or subtract the distance to be moved horizontally from x coordinate. Add or subtract the distance to be moved vertically from y coordinate.
Point P (-3, 2) moves 4 units right and 3 units down Translating a point: Point P (-3, 2) moves 4 units right and 3 units down Point P’ is now (1,-1) P(-3,2) P’(1,-1)
. Translating a shape: Rectangle moves 2 units right and 3 units down
