Answer:

option b

1.5

Step-by-step explanation:

Given in the question an equation,

y = 1.5sin4x

The amplitude of y=asin(x) represents half the distance between the maximum and minimum values of the function.

Amplitude = |a|

In the equation y = 1.5sin4x, a = 1.5

So, amplitude of graph y = 1.5sin4x = 1.5
