<h2>Answer:</h2>

The correct graph is Graph 3.

<h2>Step-by-step explanation:</h2>

We are given a modulus function f(x) by:

       f(x)=2|x|

We will go through the following graphs by checking the value of the graph at some value of x and see whether the value on the graph at that x matches the value of f(x) at that particular x.

when x=1 we have:

f(x)=2\times |1|\\\\f(x)=2

Graph 1:

When x=1

we have:

f(x)=0.5\neq 2

Hence, Graph 1 does not represent the given function.

Graph 2:

when x=1 we have:

f(x)=1\neq 2

Hence, Graph 2 is not the answer.

Graph 4:

when x=1 we have:

f(x)

Hence, graph 4 is not the correct graph to represent f(x).

Hence, we are left with Graph 3.

When we plot the function f(x) we see that it matches the graph 3.

Which statement best describes Marcos equation
satela [25.4K]
Marco's equation is correct.  Cosine is an even function, which means that for every x, f(-x) = f(x).  In other words, you get the same answer for a negative value that you would for its corresponding positive value.
