The graph for $h(t) = |t| + |t + 1|$

$h(t) = |t| + |t + 1|$ $h(-2) = |-2| + |(-2) + 1|$ ⇒ $h(-2) = 3$ $h(-1) = |-1| + |(-1) + 1|$ ⇒ $h(-1) = 1$ $h(0) = |0| + |0 + 1|$ ⇒ $h(0) = 1$ $h(1) = |1| + |1 + 1|$ ⇒ $h(1) = 3$ $h(2) = |2| + |2 + 1|$ ⇒ $h(2) = 5$ Plot the set of points: $(-2,3)$, $(-1,1)$, $(0,1)$, $(1,3)$, $(2,5)$.
