You should be able to tell if the bulb is burned out just by looking at the filament inside the bulb, if there are any breaks, the bulb is burned out.
Also if you see a black or dark spot on the glass, the bulb is burned out.
You can also use a multimeter to test for voltage coming out of the headlight / fog light connector, just unplug the connector insert the probes of the multimeter into the contacts of the connector and turn on the lights, if no reading on the voltmeter it is most likely a fuse, circuit breaker, or
the headlight / fog light switch in the car.
Your car uses D2R bulbs for the low beams which are not very expensive, you can find them on eBay or Amazon for best price.
