Let f(x) =(x − 1)2, g(x) = e−2x,and h(x) = 1 + ln(1 − 2x).

(a) Find the linearizationsof f, g,and h at 

a = 0.

Lf (x) = 

 

Lg(x) = 

 

Lh(x) = 

(b) Graph f, g,and h and their linear approximations. For whichfunction is the linear approximation best? For which is it worst?Explain.

The linear approximation appears to be the best forthe function  ? f g h since it iscloser to  ? f g h for a largerdomain than it is to  - Select - f and g g andh f and h . The approximation looks worstfor  ? f g h since  ? f g h movesaway from L faster than  - Select- f and g g and h f and h do.
