If f (x)=3^x ; g (x)=4^x , then f ^ (0)- g ^ (0) 1+ f ^ (0) g ^ (0) is

Options

  1. A( 3 4 ) 1+( 3)( 4)
  2. B( 3 4 ) 1+ 12
  3. C12 1+ 12
  4. D( 3 4 ) 1- 12

Correct answer

A. ( 3 4 ) 1+( 3)( 4)

Step-by-step solution

aligned f ^ (x)=3^x 3 & f ^ (0)= 3 ~g ^ (x)=4^x 4 & g ^ (0)= 4 f ^ (0)- g ^ (0) 1+ f ^ (0) g ^ (0) & = 3- 4 1+( 3)( 4) & = ( 3 4 ) 1+( 3)( 4) aligned
