Hello,
I was going through the same problem. From what I can see on the net, one of the relations a linear function has to express is:
f(u + v) = f(u) + f(v)
Now if f(x) = ax + b is linear then
f(u + v) = a(u+v) + 2b
So f(u + v) is not equal to f(u ) + f(v).
So why is f(x) = ax + b linear as it fails this criteria?
Sorry for this stupid question...
Thanks,
Luc
