What is the interval in which both f (x) and g(x) are positive?

Rational function f of x with one piece increasing from the left asymptotic to the line y equals three-halves and passing through the point negative 4 comma 3 and through negative 3 comma 4 to the right asymptotic to the line x equals negative 2 and another piece increasing from the left asymptotic to the line x equals negative 2 and passing through the point 0 comma negative 1 and 1 comma 0 to the right and the logarithmic function g of x increasing from the left in quadrant 4 asymptotic to the line x equals 3 and passing through the points 4 comma 0 and increasing to the right through the point 6 comma 1
