Wrong Answer Keys for Algebra II Activity Quiz LA#aqa2260 and LA#aqa2250

My son got an answer wrong on the Activity Quiz: Graphing Polynomial Functions in Chapter 5 of Algebra II LA#aqa2260. When I click the link for the answer key, it takes me to the key for Multiplying Polynomials LA#aqa2190; therefore I cannot go over the answer in question with him.

I looked at the answer key for the Activity Quiz before this one, Fundamental Theorem of Algebra LA#aqa2250, but that led to the answer key for Binomial Theorem LA#aqa2200.

BTW the links for Multiplying Polynomials and Binomial Theorem lead to the correct answer keys.

We had few evenings without sleep together with my daughter to figure this out properly. And there were some difficulties with math, related elementary algebra keys.

Actually, we decided that textbooks can help us well, but personally, I've confused, by book and only the opinion of experts

in mathematical issues https://www.assignmentexpert.com/math helped us to clarify the situation. At all, we wanna make sure we don't miss something important in Chapter 5 of Algebra II cuz, I`m gonna explain a lot of tests, for my child now, so I should understand what was the matter at first...

Thanks for your explanation
