I assume it is

f (x)

3x + 1

=--------

x²-7x+12

Factor the denominator into factors. Anytime the denominator becomes zero, there will be a discontinuity in the function, since the function at these points will be undefined (division by zero is not allowed).

The denominator factors to (x-3)(x-4) and therefore will have 2 positive roots.

Can you find them?
