Passing Values to Functions with Arguments

Look carefully at the condition of the problem

functionWithArgs(1,2)
functionWithArgs(7,9)

Look at the lower left of your screenshot, the tests are making these function calls:

a , b is for all numbers?(1,2) (7,9) is like automatic ?

every time you call the function the values in the parenthesis are assigned to a and b, the function in this way can give different outputs for different inputs
