F(x)= square root of x - 2(the 2 is not a part of the square root)/ x-4 ; x=2
decide if the given function is continuous at the specified value of s.
I assume that the function is like this:
f(x)=sqrt(x-2)/(x-4) at x=2.
lim f(x)= ...
This shows how to determine if a function is continuous at a given value.
