# Let f be defined by the formula f(x)=x^2+3/x.?

when x=0 f(x) is undefined (I think), g(x)=2 (given). Would (f+g), (fg), (f/g), and (f0g) all be undefined also?

All would except f0g because there you would do g(x) first and get 2, then do f(2) which is defined.

f(x) is undefined for x = 0, because 'x' is in the denominator of the second term, 3/x. Since division by zero is undefined, f(0) is undefined.
