Answer:
3
Step-by-step explanation:
From the general form of sine function can be expressed as:
[tex] \displaystyle \large{y = A \sin(bx - c) + d}[/tex]
where A is amplitude
b is period
c is horizontal shift
d is vertical shift
We are given:
[tex] \displaystyle \large{y = 3\sin(2x - 1) + 4}[/tex]
Since we want to find amplitude, we know that amplitude is A which is 3.
Therefore:-
Amplitude is 3
