![y = 4 + 4 x^{2}-2x^{3} Lets \ write \ it \ y = -2 x^{3} +4 x^{2} +4 ](https://tex.z-dn.net/?f=y%20%3D%204%20%2B%204%20x%5E%7B2%7D-2x%5E%7B3%7D%20%20Lets%20%5C%20write%20%5C%20it%20%5C%20y%20%3D%20-2%20x%5E%7B3%7D%20%2B4%20x%5E%7B2%7D%20%2B4%0A)
The tangential line at a certain point is just the derivative so.
![y ' = -6 x^{2} +8x](https://tex.z-dn.net/?f=y%20%27%20%3D%20-6%20x%5E%7B2%7D%20%2B8x)
. 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)
Just add them together to get the number. 100,000 + 702,083 = 802,083. 802083 is 100,000 more than 702,083.
Answer:
-63
Step-by-step explanation:
Because -9 x 7 = -63. If the signs are different then it will be negative. -9 x 7 = -63 is the same like 9 x 7 = 63. I hope this answer your question!
Y=x^2 moves right 4, down 9.
