    Help with this absolute value graph please

    When graphing x=lyl-1 do you simply interchange the y and x and have the graph starting from -1 on the y-axis and opening up like a V?

    Thank you

    Hello from a fellow Albertan

    Yes, you can do this as long as you label your axis correctly. (that is, the horizontal axis would be labeled as your y-axis and the vertical axis would be labeled as your x-axis.)

    Alternatively, if you were to still label your axis as usual (with horizontal axis as x and vertical axis as y), then you would have a V-shape with origin (-1,0) spanning outward to the right. [it's the same as if you were to rotate your paper 90 degrees to the right or reflect the graph y = |x|-1 about the line y=x]
