The graph of the function f(x)=x will show a linear line when we plot its points on the graph but the graph of f(x)=-2f(x) , it will be quite different.
What is a graph?
A graph is a collection of points on a surface where we need to join those points to plot a line of the function.
How to graph a function?
Firstly we have to find two points of f(x)=x, they will be be (1,1), (2,2)
When we put the value of the function in the other function we will find the points (1,-2), (2,-4)
We now just have to plot the points on the graph and we will be able to see graph of the function g(x)=-2f(x)
