Let ( f: R R ) be defined by ( f(x)= array cc 2 x ; & x>3 x² ; & 1 Then ( f(-1)+f(2)+f(4) ) is

Options

  1. A( 09 )
  2. B( 14 )
  3. C( 05 )
  4. D( 10 )

Correct answer

A. ( 09 )

Step-by-step solution

Given function, ( f(x)= array ll 2 x & ; x>3 x² & ; 1 So, [ array l f(-1)+f(2)+f(4)=3(-1)+(2)²+2(4) =-3+4+8=9 array ]
