PLEASE HELP WILL GIVE 15 POINTS

Step-by-step explanation:

Hello, when you have an equation like y = ax+b you know that this is a line.

In this example, the function is defined in two different intervals.

For x < 1 this is the line y = 4 + x

and for x>=1 this is the line y = 4 - 2x

At the frontier, x= 1, we have 4+1=5 on one side and 4-2=2 on the other side, we we expect a "jump" in the graph.

Except that "jump"you just have to draw lines, so if you have two points you can draw them right.

For x<1, the line is passing by (-4,0) and (0,4)

And you have to stop for x<1 so the point (1,5) is not on the graph.

for x>=1 the points (1,2) and (2,0) are on the graph and we just have to draw the line.

I attached the graph.

Thanks
