QUESTION 1 a. Find the Lagrange interpolating polynomial of degree 2 that interpolates the function $f(x)=1 / x$ at the points $x_{0}=1, x_{1}=1.2$ and $x_{2}=2 $ Write the coefficients of your polynomial in the spaces provided. (Work with six decimal places throughout.) $$ X^{2}+ $$ $$ X+ $$ b. Find the error bound/maximum error of this interpolation. Maximum error CS.VS. 1580|
