Find the linearization $ L(x) $ of the function at $ a. $
$ f(x) = \sqrt x, a = 4 $
if f of X escort of X then after four equals the skirt of four, which is to therefore f prime of four. F Prime of X is one over to squirt of acts that it's one of her too squared before, which gives us 1/4 glue. The linear realization is gonna be two plus 14 times x minus for which is gonna be 1/4 x plus one.
