(MA tvpical pattern in the Julia ecosystem is to use an optional second positional argument to pass parameters to a function. For example, the function {depending on the parameter 13} its} = casts] - 5 could be written in Julia as | HI, p=1) = costs} trip This sets the default value of the parameter to 1: out easily.r allows this value to be modied. For f as above, what is the value of f (t). 1 , 2}? (c) What is the value when no second argument is passed. f (D. 1}
