如何用mathmatica完成如下图分段函数,
f[x_] := 0 /; x <= 0
f[x_] := 10 + 2 x /; (x > 0 && x <= 10)
f[x_] := 30 /; 10 < x <= 20
f[x_] := 30 - (x - 20)/2 /; (x <= 40 && x > 20)
f[x_] := 20 /; (x > 40 && x <= 50)
f[x_] := 20 - 2 (x - 50) /; (x > 50 && x <= 60)
f[x_] := 0 /; x > 60
Plot[f[x],{x,0,60}]
f[x_] := 10 + 2 x /; (x > 0 && x <= 10)
f[x_] := 30 /; 10 < x <= 20
f[x_] := 30 - (x - 20)/2 /; (x <= 40 && x > 20)
f[x_] := 20 /; (x > 40 && x <= 50)
f[x_] := 20 - 2 (x - 50) /; (x > 50 && x <= 60)
f[x_] := 0 /; x > 60
Plot[f[x],{x,0,60}]
