Answer:
Does not exist.
Step-by-step explanation:
d/dx |u| = (u / |u|) * du/dx
Here u = x^2 - 1 and du/dx = 2x , so we have
2x (x^2 - 1) / |x^2 - 1| as the required derivative.
At the point (1,0)
the denominator = |1^2 - 1| = 0
- so the derivative does not exist at (1, 0)

Answer:
(b) (1, 1/6)
Step-by-step explanation:
The "unit rate" is always the y-value for x=1 when the relationship is proportional (as it is here).
That point is not specifically shown on the graph. It would be (1, 1/6).
B.
2/0.8 is 2.5
I would download an app called Socratic is helps a lot!
