What is a best way to show the range of a function with 4 variables

Hi all, I have a function with 4 variables. Two variables are within a range, while the other two have discrete numbers. Using enumerate method we can get some idea of the value range of the function, but that may not be efficient. I attached my worksheet with an example function in the attachment, would someone advise me what is the best and most straightforward way to probe the range of this function? Thank you!

I have find the minimum of one function on 4 arguments and would like to check it by help of 4 plots.

I have done so:

I don't think there's any better way to do it than to enumerate the cases for b and c. At least, not in Mathcad, which does not have a solver that can force a variable to be one of a number of discrete values.
