Given the points x0=0;x1=1 and x2=2 and let f be a function such that f(x0)= −6,f(x1)=−4 and f(x2)=0. Let P(x) be the Lagrange interpolating polynomial of f(x) at the points x0,x1 and x2. If P(x) is used to approximate f(x), then an approximation of f′(0.5) is most nearly: 2 None of the choices 1 0.25
