we have the following:

the first thing to do is calculate the value of each f(x)


\begin{gathered} f(-2)=2\cdot-2=-4 \\ f(0)=2\cdot0=0 \\ f(2)=2\cdot2=4 \\ f(4)=2\cdot4=8 \end{gathered}

then having each point, we join them and in this way we obtain the graph

now,

Explain how you would graph the function, f(x) = 2x using the given domain: {-2, 0, 2, 4} on-example-1
