I wonder if there is a way to set a default value in a function definition.

For example, I set up a function

f[x_, y_] := (x + y)*2

I would like to set the default value of y=5, therefore, even though I only give x equal to 1, the function will return 20.

See the documentation. Btw, any reasonable internet search such as "Mathematica function with default value" will immediately give you the answer. – user293787 Jul 23 '22 at 07:45
