How are the functions y = x and y = x – 3 related? How are their graphs related?
A.Each output for y = x – 3 is 3 more than the corresponding output for y = x. The graph of y = x – 3 is the graph of y = x translated down 3 units. B.Each output for y = x – 3 is 3 more than the corresponding output for y = x. The graph of y = x – 3 is the graph of y = x translated up 3 units. C.Each output for y = x – 3 is 3 less than the corresponding output for y = x. The graph of y = x – 3 is the graph of y = x translated down 3 units. D.Each output for y = x – 3 is 3 less than the corresponding output for y = x. The graph of y = x – 3 is the graph of y = x translated up 3 units.
They are parallell, the second line is always 3 units below the first line. Here is a graph: |dw:1348098972693:dw|
but i still dont get it:/
try out each possible answer and see if they turn out to be true
That two objects are translated in space just means that they are moved. So that the line is translated down 3 units is the same as moving the first line down 3 steps. If you think about it you should be able to figure it out.
y = x - 3 is obtained when you shift y = x down 3 units !
