if you look at the part where the first part connects with the second part:

y = 5 if x < - 2

y = -2x + 1 if -2 ≤ x < 1

we don't have a discontinuity there, so there shouldn't be a dot.

What is wrong with the graph?

When we graph over intervals like (a, b) or [a, b] or something like that, we use dots to define the end of the intervals, and to denote that the function ends abruptly or we have a jump.

In this case, you can see that between the end and the second part and the beginning of the third part there is a jump, so the use of dots is correct there, but if you look at the part where the first part connects with the second part:

y = 5 if x < - 2

y = -2x + 1 if -2 ≤ x < 1

we don't have a discontinuity there, so there shouldn't be a dot.

That is the only error with the graph.
