If the parents function is y4x which is the function of the graph?
The function y = x is the graph that passes from the points (-1,
-1), (0, 0), and (1, 1)
The function y = 4x is the graph that passes form the points
(-1, -4), (0, 0), and (1, 4)
Sketch these graphs in a same x and y coordinate system, and you
can see both of them
