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.
Awesome, Mr. Bill. Thanks a lot!

Limit of Piecewise in WolframAlpha
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}]
