If f(x)= (e^ 2 x -1 ) x⁰ x² , x 0 is continuous at x=0 , then f(0)=
Options
- A90
- B180
- C90
- D180
Correct answer
C. 90
Step-by-step solution
aligned f (0) &= _ x 0 ( e ^ 2 x -1 ) x 180 x ² [ x^ = ( x 180 )^ c ] &= _ x 0 ( e ^ 2 x -1 x ) ( x 180 x ) &= (2 _ x 0 e ^ 2 x -1 2 x ) 180 [ _ x 0 x 180 x 180 ]=2( e ) ( 180 )= 90 aligned
