Homework Statement
This is a two part problem
A) Find a vector normal to the plane at (2,1,7)
B) Find a vector normal to the plane tangent to the paraboloid at (2,1,7)
Homework Equations
Plane: z = x + y +4
Paraboloid: z = x^2 +3y^2
The Attempt at a Solution
I'm not sure where to start. I know that a vector normal to the plane is <1,1,-1>, but that isn't at (2,1,7). Any help?
