Find the derivative of f(x)=x+1/x-1 using first principal​
zepelin [54]

f ' ( x ) = 1 ( x + 1 ) 2

 

Explanation:

differentiating from first principles

f ' ( x ) = lim h → 0

 

f ( x + h ) − f ( x ) h

f ' ( x ) = lim h → 0

 x + h x + h + 1 − x x + 1 h

the aim now is to eliminate h from the denominator

f ' ( x ) = lim h =0  

( x + h ) ( x + 1 )− x ( x + h + 1) h ( x + 1 ) ( x + h + 1 )

f ' ( x ) = lim h → 0

 x 2 + h x + x + h − x 2 − h x − x h ( x + 1 ) ( x+h + 1 )

f ' ( x ) = lim h → 0

 

h 1 h 1 ( x + 1 ) ( x + h +1 )

f ' ( x ) = 1 ( x + 1 ) 2

A, B and C are integers. A minus B is even and A minus C is odd. which of the following must be odd? 
jek_recluse [69]

Answer:

C: B+C

Step-by-step explanation:

A-B is even so A and B are either both even or odd.

A-C is odd so one is even and the other is odd.

Because A is common to both cases B and C have to be of different parities.

In answer A, B, and D we are not sure of the parity of the numbers.

However, in answer C we know that B and C are of different parities, and and even plus and odd is odd.
