Find the amplitude of the solution
y=-4sin1/3x

c. 4

Step-by-step explanation:

The amplitude of a graph is basically the distance from the top of the wavelength to the bottom of the wave length. When dealing with the equation itself the amplitude is represented by the initial number being multiplied to the sin cos or tan. Since the amplitude is just the distance and direction does not matter, this value is always positive. Therefore, in this scenario, the amplitude would be 4.

1/4 and 8/3 because:

the reciprocal if 4 is 1/4 because 4 is used as 4/1 and the opposite of that is 1/4. the opposite of 3/8 is 8/3 so that is the answer.

i think this could be a possible answer (1 / 84) -1

good luck! : d
