We are give that t < -4, this is the open interval
:
( -infinity, -4)
:
if the inequality was -4 > or = t, then the interval would be
:
( -infinity, -4], this is an interval closed on the right
:
In this graph, shading would be to the left of -4 on the number line and terminated with an arrow
:
:
shading represents the solutions to the inequality
