Suppose I want to define a function $f(x)=mx+b$. And suppose I might want to change $m$ or $b$ later.
Specifically, suppose I initially want $m=-2,b=10$, but maybe will change these values later
Two ways I can think of to do this are
slope=-2; intercept=10; f[x_]:= intercept+slope*x
or, I can define it as
Does anyone have suggestions vs when to use one approach vs the other?
I usually do a hybrid kind of thing, when I use the latter way, but then define something like
slopeCase1=-2; interceptCase1=10; and then call
f[interceptCase1,slopeCase1,x], but this looks ugly is probably problematic in more ways than one.
The former way seems nicer to me, but I always worry that when I later go and change slope (say
slope=-3), some definition somewhere will not be changed because of some technicality.
- (If I am only calling
f[x_]once this is not really a worry, but if I use
fin another function, which is used in another, etc, theres a lot of places where a mistake can happen
