Question

FIND THE LIMIT

LIM l 7H l / H

HINT: EVALUATE THE QUOTIENT FOR SOME NEGATIVE VALUES OF H CLOSE TO ZERO.

Answer 1

\[\lim_{h \rightarrow 0} \frac{|7h|}{h}\]

Is that it?

Answer 2

YES

Answer 3

-7

Answer 4

Basically, you have to split it into two, but if h is approaching zero, then that means the limit doesn't exist

Answer 5

Because it will be approaching a different value from the left and a different value from the right
