Unformatted text preview: 7. (True or False) The relation 2y + x 2 = 2 represents y as a function of x. 8. (True or False) The relation 2y + x 2 = 2 represents x as a function of y. 9. (True or False) The relation |x| = |y| DOES NOT represent x as a function of y. 10. (True or False) The relation |x| = |y| DOES NOT represent y as a function of x. Solutions: 1. FALSE (try x = 2) 2. TRUE 3. TRUE 4. FALSE (degree = 3) 5. FALSE (√2) 6. TRUE 7. TRUE 8. FALSE (solve for and you get 2 solutions) 9. TRUE 10. TRUE...

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
