I am trying to plot the function $$\max(x-40,0)$$ in Wolfram|Alpha, but I can't figure out how.

What Wolfram|Alpha query URL should I use to produce this graph? Or, what similar online program could I use to produce this graph?

Try out Desmos.

Typing $y=\max \left(x-40,0\right)$ works perfectly.

Here's a link to this graph: Rendered graph

    $\begingroup$ Excel is not a graphing program. You could create a data table and use a scatter plot, if you want. Or, you could save this image and import it as a picture. $\endgroup$ – wchargin Apr 30 '14 at 2:46

Wolfram|Alpha works for me if you specify the bounds for $x$:

» plot max(x - 40, 0) from x = -20 to 60
