Definition
Functions have zeros or x-values that generate function values equal to zero.
Equations have roots or solutions that can be substituted into the polynomial in order to generate a value equal to zero.
Given:
To convert this to an equation, we set f(x) equal to zero i.e
The resulting equation is:
(1, -2, 1) is perpendicular/normal to the plane, and passes through the point (1, -2, 1), so its equation is
Answer:no
Step-by-step explanation:
