#### please show that the given function is one-to-one, and find its inverse. I have gotten this problem wrong can someone please assist me with the steps in solving

The answer needs to be checked algebraically and graphically. Verify that the range of f is the domain of f^-1, and vice versa.
f (x) = 1-(4+3x/5)
Thank you much
