Tried to input the following which I already had to simplify to fit the query length, but still not having any luck. Can't understand what is wrong with this query since based on the examples I saw, this should be understood. plot G(x,y) where G(x,y)=(10+650V(y)+3.7V(y)^2) + (39-170V(y)+134V(y)^2)U(x) + (3.3+32V(y)-36V(y)^2)U(x)^2, V(y)=(y-5)/(860-5), U(x)=(x-1)/(388-1)
I've already tried lots of variants around this formulation to no avail ...
Thanks Bill & Okkes. I discovered I could input formulas similar to what Okkes sent on this site.
I attached the file..
It would be nice if anyone could point to a paragraph somewhere that described exactly how to get WolframAlpha to consistently understand user function definitions and user variable assignments to allow shortening of input for successful evaluation.
That isn't possible. Wolfram|Alpha is designed to give verbose answers to simple inputs, not vice versa. Definitions are not an available feature. As Laurent noted, the best choice for multi-line evaluation is Mathematica or the Wolfram Programming Cloud.

But you state that is not possible.
I believe I have also seen examples of function definition in WolframAlpha, but I can't find one at the moment.
The issue seems to be finding the notation that consistently works correctly.
