This approximation is an \wordChoice{\choice{overestimate}\choice[correct]{underestimate}} because $f(x)$ is concave \wordChoice{\choice[correct]{up}\choice{down}} and the graph of $L$ lies \wordChoice{\choice{above}\choice[correct]{below}} the graph of $f$ near $a=2$.
This approximation is an \wordChoice{\choice{overestimate}\choice[correct]{underestimate}} because $f(x)$ is concave \wordChoice{\choice[correct]{up}\choice{down}} on the interval $(2, \answer{2.8}). Thus, the graph of $L$ lies \wordChoice{\choice{above}\choice[correct]{below}} the graph of $f$ near $a=2$.

The percent error,PE, in an approximation is given by
