Answer:
f(x) = x² - 6x + 14
Step-by-step explanation:
Standard form is ax² + bx + c = 0 or f(x) = ax² + bx + c
So we are going to expand the equation and combine like terms:
f(x) = (x - 3)² + 5
f(x) = x² - 3x - 3x + 9 + 5
f(x) = x² - 6x + 9 + 5
f(x) = x² - 6x + 14
The cross of the position vectors is
.. [5, 2, 2] × [6, -1, 1] = [4, 7, -17] . . . . . the normal vector of the desired plane
Since the origin is a point in the plane, its equation can be written as
.. 4x +7y -17z = 0
