The tangential line at a certain point is just the derivative so.

. At the point (1,6) we plug the x value in and get the slope at the point (y ' = 2)
The tangential line at that point is
y - 6 = 2(x - 1) (this is the answer)
Answer:
-1
—— = -0.25000
4
Step-by-step explanation:
The answer is 5/6. It can’t be simplified any further.
Lesser x is 1/2 or 0.3
greater x is 4
