    Thought working out the graph of y = | 2x - 4 | would be simple. But I got it wrong.

    How should it be worked out, as if it were a translation in the x-axis shouldn't it be y = | 2 (x - 4) |? The answer says it moves the graph to the right, I may just be being incredibly stupid but I don't see this, could someone explain it please?


    Thank you!

      I don't understand what you were trying to do. To work out the graph of y = |2x-4|, draw the line y=2x-4 and then just reflect the negative portion of the line in the x-axis.

      Yeah, I see where I've gone wrong now. Thank you.
