d) h(-3) is undefined (the point (-3, 4) is bubbled out, and there is no other point anywhere at x =-3)

e) `lim_(x>0-) h(x) = 1` (the left branch of the graphed function is approaching y = 1 when x is approaching 0 from the left.)

f) `lim_(x->0+) h(x)= -1` (the right branch of the graphed function is approaching

y = -1 when x is approaching 0 from the right.)

g) `lim_(x->0) h(x)` does not exist because the right-sided and left-sided limits are not equal, as shown above.

h) h(0) = 1 (the solid...
