Hi!
There is a function f(x) defined with rules:
f(x)=-3x if x>=5 f(x)=-(1/x) if x<5
how can I input these rules and calculate limits and show graphics of function?
Thank you so much.

Limit of Piecewise in WolframAlpha
Awesome, Mr. Bill. Thanks a lot!
Is possible type directly in wolfram alpha any sentence which could result instructions as Piecewise, or the only way is create an specific function?
Thanks, Mr. Bill. I appreciate your help.
.
f[x_] := Piecewise[{{-3 x, x >= 5}, {-1/x, x < 5}}] Limit[f[x], x -> 4] Plot[f[x], {x, 0, 10}]
