y=abolute value of x -4.

(the absolute value bar is ONLY around the x, the - 4 is outside it)

So you're supposed to be graphing y = |x| - 4...?

You should have gotten a V-shaped graph. What did you get instead? Also, what were your plot-points, including the negative values for x?

Thank you! :wink:

Please show the x-values you plugged in and the y-value you got out. Thank you! :wink:

Okay. Now what were the y-values that you got, when you plugged each of these in? When you reply, please include your computations. Thank you! :wink:
