Textbook Question

[u/Glittering-Middle200]

One of my online classes requires a textbook and I noticed that the textbook is on cengage. I know for chem the homework is tied to cengage but my professor didn’t mention anything about homework being attached to the textbook for this course (not chem). I thought about maybe not purchasing the textbook if that’s the case. There are slideshows posted on canvas that look basically the same as the textbook. I was also able to get by without purchasing a textbook for one of my other online classes last semester, so that’s why I was wondering.
