code class$=$"asciimath"$>$Is this approximation an overestimate or an underestimate? L$($x$)=$h$(2)+$h$^(\text{'})(2)($x$-2)=2^(3)+3*2^(2)($x$-2)=8+12($x$-2)(2\mathrm{.}1)^(3)=$n$(2\mathrm{.}1)$ ~~L$(2\mathrm{.}1)=8+12(2\mathrm{.}1-2)=8+12(\mathrm{.}1)=8+1\mathrm{.}2=9\mathrm{.}2$ underestimate since L$($x$)($I understand how the answer was gotten. But could you please explain why it was either an underestimate or an overestimate? I don't know what that means.$)$
