Suppose a Function Is Given by a Table of Values $\begin{array}{ccccccc}x & 1.1 & 1.3 & 1.5 & 1.7 & 1.9 & 2.1 \\f(x) & 14 & 17 & 23 & 25 & 26 & 27\end{array}$

Short Answer

Suppose a function is given by a table of values as follows:
$\begin{array}{ccccccc}x & 1.1 & 1.3 & 1.5 & 1.7 & 1.9 & 2.1 \\f(x) & 14 & 17 & 23 & 25 & 26 & 27\end{array}$ Give your best estimate of $f^{\prime \prime}(1.9)$
