What is the amplitude in the graph of y = 4sin(3x – 1) + 5?

Given the definition above and the fact that top points of the function are at y=9 and the low point are at y=1, the center line must be halfway at y=5.

the amplitude therefore is 4. it's also just half the difference of 1 and 9.

I did this graphically with desmos. Doing it algebraicly would have taken much more time i guess.

When I was thirteen years old, we left our hometown for the last time. I was forced to start high school in a strange place. It was hard, but I learned that being thrown into a new environment can be great.
