f(x)=[ x^2 x<0 [ x+2 0≤x≤2 [4 x>2 I want to draw a graph of this function through Wolfram Alpha. I googled it for 3 hours, but I have no idea. I'd appreciate it if you could tell me the commands to enter. Attachments: wolfram com.png wolfram com2.png

Thank you for your thoughtful response. I copied and pasted it, and it appeared immediately.

This might be what you want. `f[x_] := Piecewise[{{x^2, x < 0}, {x + 2, 0 <= x <= 2}, {4, x > 2}}] Plot[f[x], {x, -4, 4}]`

WA understands some Mathematica commands. You can search for those commands here Searching for piecewise there provides documentation. This appears to work in WA piecewise[{{x^2,x<0},{x+2,0<=x<=2},{4,x>2}}]
