Right, but I don't think you understand how extremely vague your request is. You are asking help with "math". Grade 11? Still doesn't help me help you, that could include about 15 classes.
What subjects SPECIFICALLY are you studying? Functions is still extremely vague, that could be almost anything. Do you understand what we need to help you?
It's kind of like if I said I needed help with "college history". Obviously there are thousands of subjects in that category.
