What is the amplitude of the function shown on the graph below?

amplitude of the wave is 2.

Step-by-step explanation:

Given : Figure of wave .

To find : what is the amplitude of the function

Solution : We have given a figure of wave

Amplitude : The amplitude of a wave refers to the maximum amount of displacement of a particle on the medium from its rest position.

We can see from the given figure that wave is maximum at up to y = 2

So, the amplitude of the wave is 2.

Therefore, amplitude of the wave is 2.

step-by-step explanation:

abc

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
