there's this thing in calculus called limits breh...
Limits are what a function approaches regardless of what the function equals. Take this function. x^2 for any real number =/0. At x=0 it takes on the function x-1000.
What's the limit as x->0? Well 0 ofc. What's the value at x=0? -1000..
Therefore argument invalid.
