## Let fx be a polynomial of degree 4

Dec 1, 2009 3 and 4 (a.k.a. cubic and quartic equations) in a way connected to Galois Let f( x) = x3 + bx2 + cx + d, with b, c, d ∈ K, be a polynomial of  Low degree polynomial equations can be solved explicitly. is a quadratic function, a degree 3 polynomial a cubic, a degree 4 a quartic, and so on. To illustrate, this consider the two functions f(x) = 3 x3 - 5 x2 + x +1 and g(x) = 3 x3.

f(x) is a polynoimial so it will be continous everywhere , now f(-1) and f(1) are of opposite sign so , atleast one rootb in (-1,1) , similarly at least one in (1,2) and atleast one in (2,4) so atleast three roots will be there But as f(x) is 3rd degree polynomial so it can't have more than 3 roots . so exactly three roots will be there Let f(x) be a polynomial function such ... - Wyzant Tutoring I completely agree with George's method, and it does work for this case because it was stated that this is a polynomial function. But for more general cases, here's how you would approach this problem. LECTURE 3 LAGRANGE INTERPOLATION • No matter how we derive the degree polynomial, • Fitting power series • Lagrange interpolating functions • Newton forward or backward interpolation The resulting polynomial will always be the same! x o fx o f o x 1 fx 1 f 1 x 2 fx 2 f 2 x N fx N f N Nth N + 1 gx a o a 1xa 2x 2 a 3x 3 a Nx = +++++N a i i = 0 N N + 1 Nth

Mock Tests for JEE Based on New Pattern. Let f(x) be a polynomial function of second degree. Sequences Let the polynomial be f(x) = ax2 + bx + c. Given, f(1 )  Let D be the set of all vectors in the plane whose x-coordinates are For example, p(x, y)=2x+4y+5 is a degree 1 polynomial in two variables. So are q(x, y ) = -2x + 3, f(x, y) = y, and g(x, y) = x - y. Degree 1 polynomials are often called linear  Figure 4: A plot of f(x) = ex and its 5th degree Maclaurin polynomial p5(x). □ Let f be a function whose n + 1th derivative exists on an interval I and let c be in. polynomials in degrees 3 and 4 over fields not of characteristic 2.
