A graph was reflected in the line y = x . Its reflection image is shown. Determine an equation of the original graph in terms of x and y. 6) 7) The key point (12, -5) is on the graph of y =f(x). Determine the coordinates of its image point under each transformation. a) y=f(-3x) by =f (3x) 8) As a result of the transformation of the 9) The point A(6, 5) lies on the graph of graph of y = f(x) into the graph of y= f(x). What are the coordinates of its y=-2f(x +5) - 8, the point (2, 5) image A' on the graph of y =f"(x - 2) ? becomes point (x, y). Determine the value of (x, y). 10) For y = f(x) as shown, graph the 11) The graph of the function y = f(x) is following: y= -f(x - 1) +4 given. Graph the following transformations of the function y-5-2 -(x-6). Show each stage of the transformation in a different colour. .2
