Thanks, piecewise function is what I need.
Hi Piotr,
Try these:
http://www.wolframalpha.com/input/?i=plot(piecewise(%7B(2%5Ex%2B3,+x%3C%3D1),+(3x%2B2,+x+%3E1)%7D)) http://www.wolframalpha.com/input/?i=plot(piecewise(%7B(2(x%5E3-x%5E2)%2Fabs(x-1),+x!%3D1),+(2,+x+%3D1)%7D)) http://www.wolframalpha.com/input/?i=plot(piecewise(%7B(1%2Fln(x),+0%3Cx%3C1),+(0,+x+%3D+0)%7D))
