EQ is something that needs to be adjusted to the sonic situation. You can't just be given a bunch of numbers for the settings and have it be good on every bass, and every amp, for any particular genre, in every room.
You have to listen to your bass through your amp without EQ and determine what frequencies it needs more of, and which ones it needs less off, and then adjust the EQ accordingly... and then understand those settings will probably change when you need to fit in a mix with other musicians... and change again when you take your rig to a different room/venue/space and play it there.
And if you haven't developed an ear for which frequencies sound like what yet, don't worry, that comes through experience and experimentation. So like @Fuzzbass said, start moving the sliders up and down and listening to what they do, and seeing what works and what doesn't.
Also, pro tip: boosting all EQ Frequencies is the same as just boosting your gain. (Same goes for cutting everything: It's just lowering the gain.) So if you think it sounds better with all the bands up, bring them back down to 0dB and just turn up your amp. Use the EQ to selectively add and remove just enough of the bands that need it.
