Step-by-step explanation:
Answer:
12 units
Step-by-step explanation:
We would need to ignore the 3 first of all. We know that 3 is located at the same place. We then need to see 7 and -5. The distance from zero of each numbers matter, not the ammount. So (-5) is 5 from zero. (7) is 7 from zero. 5 + 7 = 12 units
Without knowing anything else about
, neither of these need be true.
Suppose

Then (I) isn't true because, while the limit exists as
and is equal to 7, we have
, so
is not continuous there.
(II) also true because
is not differentiable at
; that is,

but

which means the derivative does not exist at
.
