Question

What is the amplitude for the function y=-1.5sin(4x-3pi)

Answer 1

The function given is,

`y=-1.5\sin (4x-3\Pi)`

The general form of the sine function is,

`y=a\text{ sin}(bx+c)`

Here, a represents the amplitude.

Compare the general form of function with the given function,

The value of amplitude obtained is,

`a=1.5.`

Ignoring the negative sign.

The correct option is D.
