The answer for number 19 on this homework is wrong. It should be no, that this is not a function because (1,2), (2,2), (1,2) is not a function.

The answer to #57 classwork (combining functions and compound functions) appears to me to be wrong. Would you kindly send me an explanation?

Thank you for your response regarding #57. Our next question is regarding #70 in the homework.

Dear Tammy Haenn, Yes, I agree that question #70 also did not have the correct answer. The negative sign in front of "7x" was not taken into account when the original solution was calculated. The solution to this problem has been updated in the file & the file has been re-posted. Kind regards, Audra

I believe #38 may also be incorrect. g(5) would be 7 and f(5)would be 16, so I believe the answer should be -9.

Dear Tammy Haenn, Thank you for your comment. I agree that the solution to #38 needed to be changed to your recommended solution of -9. The file has been updated and posted with the date stamp of 2020-01-10. Kind regards, Audra

In the Sequences as Functions classwork, I believe the solution to 88a should be -5 and the solution to homework #99 should be 2 + 5(n-1). Thank you for your quick responses!

Dear Tammy Haenn, Thank you for your comment. I agree with the suggestions for the solutions of 88a and 99. Those solutions have been updated and posted. Kind regards, Audra
