[Answer] If f(x) = 2x2 + 1 what is f(x) when x = 3?

Answer: 19

Most relevant text from all around the web:

If f(x) = 2x2 + 1 what is f(x) when x = 3? Therefore let f ( x ) = g( x ) = 2x + 1 . Then f ( x )g( x ) = 4x 2 + 4x + 1 = 1 . Thus deg( f ⋅g) = 0 which is not greater than the degrees of f and g (which each had degree 1 ). Since the norm function is not defined for the zero element of the ring we consider the degree of the polynomial f ( x ) = 0 to also be undefined so that it follows the rules of a ... Sep 23 2001 · For instance when D is applied to the square function x ↦ x 2 D outputs the doubling function x ↦ 2x which we named f ( x ). This output function can then be evaluated to get f ( 1 ) = 2 f … The Hessian matrix of a function f is the Jacobian matrix of the gradient of the function f ; that is: H( f ( x )) = J(∇ f ( x )). Applications Inflection points. If f is a homogeneous polynomial in three variables the equation f = 0 is the implicit equation of a plane projective curve. f(x) - Wikipedia the free encyclopedia Degree of a polynomial - Wikipedia Jacobian matrix and determinant - Wikipedia Derivative - Wikipedia More formally f = g if f ( x ) = g( x ) for all x ∈ X where f : X → Y and g: X → Y. [8] [9] [note 4] The domain and codomain are not always explicitly given when a function is defined and without some (possibly difficult) computation one might only know that the domain is contained in a larger set. ...
