Amplitude = 3

Step-by-step explanation:

The given function is : y = 3sinx

We need to find the amplitude of the given function.

The distance between the center line of the function and the top or bottom of the function is called its amplitude.

In this given function, the amplitude of 3. Hence, the correct option is (b).

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
