Use linear approximation, i.e. the tangent line, to approximate16.3 as follows:

Letf(x)=x. Find the equation of the tangent line tof(x)atx=16

L(x)= ____________________Using this, we find our approximation for16.3 is_________________

NOTE: For this part, give your answer to at least 9 significant figures or use an expression to give the exact answer.
