Jungshik Shin F2021UPG101-093 Final Exam is due on Tuesday, December 07, 2021 at 12:00pm. The number of attempts available for each question is noted beside the question. If you are having trouble figuring out your error, you should consult the textbook, or ask a fellow student, one of the TA’s or your professor for help. There are also other resources at your disposal, such as the Mathematics Continuous Tutorials. Don’t spend a lot of time guessing – it’s not very efficient or effective. Make sure to give lots of significant digits for (floating point) numerical answers. For most problems when entering numerical answers, you can if you wish enter elementary expressions such as 2∧ 3 instead of 8, sin(3 ∗ pi/2)instead of -1, e∧ (ln(2)) instead of 2, (2+ tan(3))∗ (4− sin(5))∧6−7/8 instead of 27620.3413, etc. Problem 1. (1 point) Which of the following graphs represents a relationship where y is a function of x?
