I want the answers asap. Especially the graphs.

21. f (x ) = 4( x-2) (x+ 3)3 *(x- 1)5 22. f ( x ) = - 3x2 (x + 1) 6 (x-2)* (x + 4) 4 19. f(x) = (x-2)(x-3)3 x(x + 1)> 20. f (x ) = ( *+ 2)* ( x + 3) 2 *2 (x-1)3 Ay X X X lim a. f(x) = lim lim x - 0+ a. a. x-1+ J ( x ) = x-1+ J ( X ) = lim a. X -2+ f(x) = lim b. lim lim b. X-0 f(x) = b. f (x) = x- 10 f (x ) = lim b. x- 2 f(x) = lim lim C. f (x ) = lim C. lim X-0 C. x - 1 J ( X ) = x - 1 J ( 0 ) = C. X -> 2 f(x) = lim lim d. lim d. f (x ) = f (x ) = lim x - 00 d. *-7 00 f (x) = * -00 d. x -7 0 f ( x ) = lim lim e. e. f(x ) = lim *- -00 f (x) = lim * - - 00 - e. x- -00 f (x) = e. X -00 f(x) =
