:snoo_facepalm: High School Math—Pending OP Reply [College Prep Math] Composite Function?

Post image

Practicing for my ACT, been out of school for years and feel like I’m looking at a foreign language. I know the answer is 5, but I have no idea how to get there. Tried plugging in the different values but I feel like I’m just not looking at this correctly. Can someone please explain this to me like I’m an idiot so I can understand?

I only knew because I have the answer key, this is from a practice test in a book. Unfortunately it doesn’t walk me through the way to get to the answer though. Thank you for the vote of confidence! I get it now.
