    You are right. The problem is wrong, and the given solution is wrong. It is a voltage follower with a gain of 1. If the writers wanted to show a non-inverting amp, then they should have put R1 on the other side of R2.

    Yes, voltage follower. R1 is on the wrong side of R2 to be an amplifier. R1, as shown, is just the load.

    GIGO principle in effect here: Garbage In, Garbage Out. You should find another text book with accurate pictures and text. If you have an instructor, ask him or her to discard this one to the rubbish heap. How many more errors have you found in this text book? Is it your job to correct the author's mistakes in proofreading?
