Which of the following inequalities does the graph represent?
(i added a picture)
a.
3 ≤ t ≤ –1
b.
3 ≤ t < –1
c.
3 > t ≥ –1
d.
3 ≥ t > –1

So we assume that the inequaity represents the shaded reigon

you have to know the meaning of the line
the line goes from -1 to 3 so t is more than -1 and less than 3 so -1>t>3,
but there are special points
the point where the line stops at -1 is shaded in meaning that values above -1 and including -1 are in the solution -1<t

the other point at 3, is not shaded in, meaning that points below 3 and not including 3 are included so t<3

the solution is -1<t<3 or 3>t>-1 or C
