Hi,

Let's say I've defined a function f[c]=c*x^2

when I try to plot this directly,

Plot[ f[3], {x, -10, 10} ] 

it doesn't plot anything.

But when I assign function to a variable,

v1=f[3]; Plot[v1, {x, -10, 10}]

then there is no problem. But I dont want this. Is there any way to plot directly from a function?
