Question

What is the amplitude of the graph of y =3 sin (2x - 1) + 4?

Answer 1

Answer:

3

Step-by-step explanation:

From the general form of sine function can be expressed as:

$\displaystyle \large{y = A \sin(bx - c) + d}$

where A is amplitude

b is period

c is horizontal shift

d is vertical shift

We are given:

$\displaystyle \large{y = 3\sin(2x - 1) + 4}$

Since we want to find amplitude, we know that amplitude is A which is 3.

Therefore:-

Amplitude is 3
