If f varies directly as g and inversely as h, we can write the equation as:

f = k * (g / h)

where k is the constant of variation.

To find the value of k, we can substitute the given values of f, g, and h into the equation:

-12 = k * (-3 / 4)

Simplifying:

-12 = k * (-3/4)

Multiplying both sides by -4:
