Salaam alikum!
I have taught Mathematics in various countries, including the Arab countries. I have also tutored to the students in the US, online. I know the topics mentioned in your post, viz., rational exponents and radicals, graphing and solving radical equations, inverse of functions, and preforming function operation, very well. Just assign this task to me and rest assured that it is done to your complete satisfaction. Looking forward to a hearing from you. Thank you!
