Final answer:
To find f(-1) using synthetic division, set up the synthetic division table and find the remainder in the last row, which will be the value of f(-1).
Step-by-step explanation:
To find f(-1) using synthetic division, we can set up the synthetic division table as follows:
To find the angle of intersection between two planes, calculate the angle between their normal vectors using the dot product and magnitudes
17 -2 -17
-1 |
-17 19 -2
0 -19 21
-21 0
The remainder in the last row is the value of f(-1), which is 0. Therefore, f(-1) = 0.
