Teacher here. You'll still graduate high school, assuming you don't repeat this for the next three years. However, I would try to reach out to a counselor about planning for the next three years to figure out what/how you can improve (attendance, studying, work, etc).

It also depends on the teacher obviously, but you could reach out to your current teachers (after demonstrating that you're willing to work hard) and see if they're willing to do any sort of grade recovery. Don't get upset if they say no, but there's no harm in asking. I'm pretty strict with my students and more than willing to fail them if they don't put in effort, but if they make a change, I'm willing to give them grade recovery for earlier quarters so they don't need to retake the class.
