How do I find the instantaneous velocity at a specific time (ex: t=2 seconds) using average velocity? Here's an example of what I mean:
What is the instantaneous velocity at t=2 seconds? Do this by finding the limit as h->0 of the average velocity 3h-6.

Thanks in advance!

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5

the answer

b. they are parallel and will never intersect.
