Find the amplitude of y = -4 sin x.

The amplitude is 4.

Step-by-step explanation:

Given the form of the sine function:

Where is the amplitude, is the period and "k" is the vertical shift of the wave.

You know that, in the sine function given ( ), you can identify the amplitude and the period. These are:

Therefore, the amplitude of   is:

just find the gcf and solve the gcf's until you get each answer i have a really good feeling somethings missing xd (like the dimensions of the fence) *cough *cough *hint *hint

step-by-step explanation:

its 4 because 2 times 2 is 4, if you double the number two you get four
