Question:How do I plot a function that includes parameters that can be changed by the user

I am trying to plot a function f(x).  Within the definition of f(x) I have some parameters, e.g., a, b, c tha have been defined.  Then these three parameter define a new parameter R.

The function is f(x)=R x.

 

 

a := 1;              Define a
1

b := 2;              Define b
2


c := 3;               Define c
3

R = a+2*b+3*c; Define R from a, b, c

R = 10 + 2 b~ (it should had given me 14)

F(x):=R*x;  Define the function
x -> R x


plot(R*x, x = -5 .. 5);   RECEIVE ERROR
Warning, expecting only range variable x in expression R*x to be plotted but found name R

 

 

I also tried to define R as R(a,b,c) and then F as F(R,x)...

but still it doesnot work.

Can anyone direct me to the right solution?

 

Thanks in advance.
