Please solve these 2 question in details and fully explaination.

1. For the function f( x ) given below , find the desiative ( f " ) ( c ) at the given pointc, by first finding a= f"(c) If fla ) = 3x + 10x and c=-13 then as ? Using this result, ( 5 ) ( c ) = 2 2. Let f(x ) = x x (9x - 13 ) 5 14x2 - 1 If we use the method of logarithmic differentiation to find f'(x ), I've obtain f ( x ) in the form f le ) - * (9x - 13)5 ( Ala) + Ble ) ( (x) 14 x 2 - 1 92- 13 4 x 2 - 1 where A(x) , B(x) and (( ) are functions of x. Find them
