limit fungsi kelas 11 ips bantu yaaa

3.)   limit        = 3x^2 - 6x +8
         x→2      = 3. 2^2 - 6.2 + 8
                      = 3. 4 - 12 + 8
                      = 12 - 12 + 8
                      = 8

5.)   limit                  = √7x -5
         x→3               = √7.3 - 5
                               = √21 - 5
                               = √16
                               = 4

6.)  limit                  = (3x+5) ( 1-x)
       x→2                = ( 3.2 + 5) (1-2)
                              = ( 6+5) (-1)
                              = 11 (-1)
                               = -11

semoga membantu
