Solving real-life problems with limits can be tricky for a few reasons:

1. Difficult Functions: Figuring out how functions act when $x$ gets close to a certain number can be hard. This often makes understanding the limit confusing.

2. Indeterminate Forms: Sometimes, we run into situations like $0/0$. This can make finding limits more complicated.

3. Graphing Limits: Seeing limits on a graph takes a good understanding of how functions work. Many students find this part tough.

But don’t worry! You can tackle these challenges by:

• Learning helpful tricks like factoring, rationalizing, or using L'Hôpital's Rule.
• Practicing with different functions to get a better feel for limits and how to use them.
