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

Answer:
3 ≤ x ≤ 7 or x is between 3 and 7, inclusive
Step-by-step explanation:
Eira's graph probably resembled the diagram below.
The domain is the set of all possible x-values that will make a function work.
x can take any value from 3 to 7.
The domain is [3, 7] or 3 ≤ x ≤ 7.
