Standard form, move the variables to the left-hand-side, leave the constant on the right-hand-side, usually the "x" comes first,

The cosine function is negative in 2nd and 3rd quadrants, So you know that you will have 2 solutions. One between pi/2 and pi, the other between pi and 3pi/2.
Refer to a unit circle to find that

Final Answer:
The functions y = -4sin (x) and y = 4sin (x) has the given properties.Functions help to define the relationship between the independent and the dependent variable.
<h3>What is function?</h3>
A expressions defining a connection between the independent variable and dependent variable is known as the functions.
A feature that:
The domain is defined as the set of all real numbers.
a single x-intercept
The amplitude is four.
The y-intercept is defined as (0,0)
Because the specified function goes through the functions having "cosine," the functions containing "cosine" can be omitted from the selections (0,0). As a result, we have two options:
Hence y = -4sin (x) and y = 4sin (x) has the given properties.

x-y=-2 y=x+2
2x+y=8
2x+x+2=8
3x=8-2
3x=6
x=2
y=x+2 y=2+2 y=4
